Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Tyler, there have been many comments abt how we would know how to find the density of iron if were in an exam but there hasn't been a reply, could u reply cause its a important question
hey tyler, got a question, in general not everyone knows what's the density of iron, but what if this kind of question came out in an exam, u cant google stuff with ur phone right , so i was wondering is there another method to know the density of an element based on the question
I think it is impossible for this type of question to come u should have at least 2 variables without them u can't do the question and by the way your teacher can't for example give u a question like Find the mass of the object so based on that question you should have density and length in the question
Your vd are so helpful for me. The chapter-end test is going to come within two days and your explanation helped me for revision. Thank you so much. I mean it .
+Ana Patino he only needed three significant figures because 275 and 7.87 both have three sig figs. If he kept it as 2164 it would've had four sig figs. you always want to write your answer with the least amount of sig figs possible.
codina doesminecraft A 0 is significant depending where it's at. Any zeros after the decimal or in between two non-zero numbers are considered sig figs. If a number ends in 1 or more zeros and ends right before the decimal point then it's not considered a sig fig. For example 100 has only 1 sig fig, but 100.00 has 5. So in your case the answer would just be 1.2091
Can u please solve this question : A graduated contains 35.5 cm cubic of water . what is the reading of the level of water after 19g of silver metal is submerged in the water ? Please
The thing here is that we want to know how to get that iron's density ourselves without internet, because....yeah in life we can use any trick that gets the job done, but for a stupid test we can't use certain resources....and school is the main issue why most of us are here...

Tyler DeWitt I'm just a kid
Ai
With my science teacher and my math teacher, i couldn't understand this, but now i do thanks to you!
I should just skip school and start watching your videos, they are way better and easier to follow than my teacher
Ok yeah I so much I agree with you,he's awesome!
Go one 😊
Thank u so much, my chem teacher kinda blows, so I have been looking for something like this for like an hour!! U r a lifesaver

yes
Very helpful. Thank you. I have watched a few of your videos. They are easy to follow and you explain as you go. Thanks again.
you have a gift for teaching and making this easy for us right brainers too :) Thanks sooo much!
Your vd are so helpful for me. The chapter-end test is going to come within two days and your explanation helped me for revision. Thank you so much. I mean it .
This man just saved my life 😭
sir , why liquid are stored in cylinders? why not in a rectangular shape container?
Wow amazing 👏👏 l love your teaching style
love your teaching style!
You are great teacher
When we have a material which is denser than another one, does this mean that it has more number of atoms per one cm^3 ??
Thank you I love your videos I hate physics but your videos are really easy to follow
You are good explainer sir
thank u for the help Tyler it would mean alot
Thanks it was really easy to follow
Thanks a lot u help me understand my work in a better easier way.
How are we supposed to get the density if we are doing a test? I guarentee phones are not allowed on an exam.
J.R. Navarro idk what test you're doing but we're allowed phones!
J.R. Navarro surely you're given a data/formula sheet to refer to, otherwise it should be stated in the question.
TheTman9898 But if we are given a question like that how are we suppose tk find the density??? Please anwpswer my exam is tomorrow
the teacher would probably give you the density
Why don't we use the 150 ml to determine our significant figures for the answer?
+Rose Smith true
Yeah, wouldn't it be 280mL not 275mL ???
Why, why not?
How did you get the density. My final EXAM is tom
did you pass?
Thank you!!! You rock!!!!!
when he rounds the final result why is it 2,160 and not just 2,164?
+Ana Patino he only needed three significant figures because 275 and 7.87 both have three sig figs. If he kept it as 2164 it would've had four sig figs. you always want to write your answer with the least amount of sig figs possible.
+Ivan Mendoza thank you! makes perfect sense to me now
so 0 is not consider as a sig fig. so if 54561 / 45124 = 1.20910000 instead of 1.20913483??
codina doesminecraft A 0 is significant depending where it's at. Any zeros after the decimal or in between two non-zero numbers are considered sig figs. If a number ends in 1 or more zeros and ends right before the decimal point then it's not considered a sig fig. For example 100 has only 1 sig fig, but 100.00 has 5. So in your case the answer would just be 1.2091
3 significant figures?
How did you get Destiny
What I want to know is HOW to derive the density from the periodic table of elements, specifically from the atomic mass.
Is anyone else's midterm coming up so they are just binge watching his videos to study. cause same.
wow, i just now understood that cm^3 and ml are the same.
Why is the final answer 2,160? Do you just get rid of the 4?
Tyler, can i ask how did you get the density of Iron
very helpful Thanks you excellent teacher
would 2160 need to be written 2.16 x 10^3 ?
I don't think so
Can u please solve this question : A graduated contains 35.5 cm cubic of water . what is the reading of the level of water after 19g of silver metal is submerged in the water ? Please
Pazizsha Shaziz 19g divided by 35.5 is density
1.87
Thank you so much for the help x
Www.
Г· ္ုဘိ
great video
Thanks!!! So useful
How did you find the density of the iron? 😱 without the mass? 😥 without even looking on the internet? 😥
He either knew it, or he looked in a book or on the internet
He said it himself that you could just look it up.
you cant do that during a test
The thing here is that we want to know how to get that iron's density ourselves without internet, because....yeah in life we can use any trick that gets the job done, but for a stupid test we can't use certain resources....and school is the main issue why most of us are here...
he said that he got it from the internet
I don't know how density from?
thanks you are so smart
thx you are helpful
is it possible to find the density without checking it in the internet or from a book? o.O
Amazing
can someone enlighten me on how he get 7.87g/cm^3 ??
Mickaela Rodas he get it online
1mL=1cm^3. He converted mL to cm^3
❤️🙏
If u can search up the density online, why not just search up the mass....
Lol right
ur my god
college Chemistry vs Tyler DeWitt hmmmm? Tyler DeWitt is my choice tbh...
siuuu
Why each video equally many digits? Dont u want variation? Dont u know the topic good? Why repeat urself?
