Some of this seems a bit fast and too complex. I am 9 years out of high school, took physical, biology, chemistry, and oceanography, passed all but chemistry with an A. Hoping after watching this I will have picked up at least some knowledge. I’m also using a study book. We’ll see 😅

12:21 The Mole: To answer this question, first you need to understand mole and molecules are 2 different things. A mole tells you how many molecules you have. Think it of a "dozen" of eggs with an egg itself is a "molecule". In this question, there are 2 parts to answer. First, how many moles are in 8 ounces of water: To answer how many moles of something, we have the formula: Moles of "something" (water in this case) = Mass of something (water) / Molar Mass of something (water). Molar Mass of Water = 2*1 (2 Hydrogen atoms in a water molecule) + 1*16 (1 Oxygen atom in a water molecule) = 18 g/mol * Just a side note: you can call water a molecule, but H and O are called atoms. Because in definition, A molecule is a group of two or more atoms bonded together, representing the smallest unit of a chemical compound that retains its properties. +Now we have both Mass and Molar Mass of Water, we can apply to the formula above, which gives us: > Moles of Water (in 8 ounces of water) = 227.72 / 18 = 12.6 (moles) | mole is the measurement unit here because the units for grams in Mass and Molar Mass canceled each other out! >>> That answered part 1 of the question. Now let's move on to part 2. +First, we have the conversion from Avogadro's Number: 1 mole of something = 6.022*10^23 molecules of something. > There are 12.6 moles of water in 8 ounces of water, therefore, >> 12.6 moles of water = 12.6*6.022*10^23 is approximately = 7.58*10^24 molecules of water. (You can say: there are 7.58*10^24 molecules of water in 8 ounces of water) >>> After using the number of Moles of water in 8 ounces of water, which is 12.6 (moles), multiplied by Avogadro's Number, we get 7.58*10^24 molecules of water are in 8 ounces of water (equivalent to the number of molecules of water are in 12.6 moles of water). We have 2 Hydrogen atoms are in each water (H2O) molecule. Then, we can simply multiply our numbers of molecules of water to find the numbers of Hydrogen: 2*7.58*10^24 = 1.52*10^25 (Hydrogen atoms in 8 ounces of water). I hope this finds its way to assist you to understand the mole topic :)

I need someone opinion I'm struggling on what branch I want to see combat but I also don't want to be stranded in a chair I'm considering all branches I look at some of the pros and cons
I went to marine bootcamp, I highly recommend marines but my dad was military for 23 years and he tells me that every branch can be good you just have to experinece for yourself what branch and job you like the most.
@@MometrixTestPrep I absolutely did. It still required me to find another video that did a better job of explaining the concept. I’m not trying to be rude, I’m just suggesting that you listen to the feedback and make adjustments. I’ve read through the comments. I’m not the only person with this takeaway.

Thanks i'm gonna listen to this entire series over and over again. Need that bonus.
Yall did great alternating people, I wasnt bored listening one individual person

I've been watching this since before getting my reviews for asvab, so I'll ace it up
How did you do
@@lilricky5483 I didn't enroll, my recruiter wanted me to run medical exams before actually enrolling to make sure I didn't have any medical issues, but in one of those the pulmonary test revealed I have asthma and that's a disqualifyer
@@GloryJonaticDaaaaamn. That sucks dude. Hope you can find something else you want/love to do.
@@GloryJonaticsad but at least now you know you have asthma
@@GloryJonatic hope everything worked out
I have my asvab one week from now, wish me luck!
edit: Scored a 98 and I qualify for every enlisted job. Currently a high school jr so enlistment is a long time away
good luck
How did you do?
@@Im.just_aj_3 I got 98 and qualify for every single enlisted job!
How did it go ?
@@violetsure3898 They prolly got sent out to BMT already lol
i really wish i went straight into the military fresh out of high school 😅
Because babiii ill struggling
Going for navy EOD and definitely learned a few things
when do u go to meps? im going on the 18th and 19th. going for navy corpsman
@@isaiahgonzales8564 how was it?? I go to meps tmwr and I’m going for corpsman to
@@maelingx Good luck. I go next Monday. Let me know how the ASVAB was
How’d everyone do? I also want to go for corpsman
@@Syndra_how was it?
53:49 so that’s what happens to my blankets and some clothes when they come out of the dryer?
failed my first general; science practice test, taking the real thing next week, will update you with the results.
How'd it go?

* Just a side note: you can call water a molecule, but H and O are called atoms. Because in definition, A molecule is a group of two or more atoms bonded together, representing the smallest unit of a chemical compound that retains its properties.
+Now we have both Mass and Molar Mass of Water, we can apply to the formula above, which gives us:
> Moles of Water (in 8 ounces of water) = 227.72 / 18 = 12.6 (moles) | mole is the measurement unit here because the units for grams in Mass and Molar Mass canceled each other out!
>>> That answered part 1 of the question. Now let's move on to part 2.
+First, we have the conversion from Avogadro's Number: 1 mole of something = 6.022*10^23 molecules of something.
> There are 12.6 moles of water in 8 ounces of water, therefore,
>> 12.6 moles of water = 12.6*6.022*10^23 is approximately = 7.58*10^24 molecules of water. (You can say: there are 7.58*10^24 molecules of water in 8 ounces of water)
>>> After using the number of Moles of water in 8 ounces of water, which is 12.6 (moles), multiplied by Avogadro's Number, we get 7.58*10^24 molecules of water are in 8 ounces of water (equivalent to the number of molecules of water are in 12.6 moles of water). We have 2 Hydrogen atoms are in each water (H2O) molecule. Then, we can simply multiply our numbers of molecules of water to find the numbers of Hydrogen: 2*7.58*10^24 = 1.52*10^25 (Hydrogen atoms in 8 ounces of water).
I hope this finds its way to assist you to understand the mole topic :)
moles and avogadro's law just took me right back to all the math i did in ap chem. I'm glad I atleast understand what's going on lol
Is any of this actually in the asvab??

Will this help me pass the asvab
Yes
@@arkhamknight6306are you sure? I truly want to be military police
@@itsjodi9939 It certainly does help but don’t use this as your only resource you study from, it won’t guarantee a pass but it did help me pass.
@@itsjodi9939how did you do please let me know
No you will fail if you watch this

Did a great job explaining everything
I need someone opinion I'm struggling on what branch I want to see combat but I also don't want to be stranded in a chair I'm considering all branches I look at some of the pros and cons
Bro same😂what’d you go with? I did army because of my tatt
@@maanlowk4882 I'm probably doing army or marines leaning more towards army because I was in rotc and our branch was army
I went to marine bootcamp, I highly recommend marines but my dad was military for 23 years and he tells me that every branch can be good you just have to experinece for yourself what branch and job you like the most.
I was waiting for ABC questions 😢
Asvab test is to hard
Science isnt my thing so i may need to watch this more then once lol
hopefully i don't get a question about moles...
The information is too technical to move at the speed of which its explained.
Feel free to slow down the playback speed in your settings if that is helpful for you!

@@sabrinaslaughter3312I agree with you completely! It’s way too fast paced and I can’t keep up. Waaaay too fast.
That's it, I'm ready to drink the coolaid!

Hey guys just curious, has this helped any of you guys pass this portion?
Yes!!
Where's the third law of motion lol
