thanks so much!! this video made rounding sooo much clearer and when I thought I knew enough, well, I didn't. the video helped me strengthen my knowledge! AND it's so easy to follow along...I don't even have to take notes!! just jot down a few things in my head. this video is definitely not a waste!
I still have one question, what should you do if you had to round 773.87 down to 3 significant figures? Would you leave the decimal at the end or should you just leave it off?
@@abbymae8334 i think the last zero is a place holder. idk i am just learning this stuff? Edit: nvm i did not see that u comment 11 months ago lol. Did u pass chem?
You would round 773.87 to 773, because the three digits are significant without the presence of a decimal. The purpose of a decimal for trailing zeros is to convey their significance; however, since we're looking to round this number to 3 significant digits--any trailing zeros resulting from rounding aren't significant so there shouldn't be a decimal. You could keep the decimal after 773, but it would be redundant because the three digits themselves already have significance.
The question says to round to two significant digits and 0.0560 would be three. The trailing zero (the one at the end) is significant because of the decimal. Check out this video: th-cam.com/video/pFl49nIGQF8/w-d-xo.html
i honestly have learned so much here thank you so so so so so much!!!
That's great news, Irving! Be sure to visit www.GetChemistryHelp.com for even more videos, worksheets, and help with Chemistry! :)
I was having issues with this while trying to study, but now I think I get it! Thank you!
Thank you TwT Been trying to solve this all day. Struggles of being a junior high schooler.
Thank you so much sir you’ve helped me drastically 🙏🙏

Glad I could help! Please share with a classmate. 🙂
Thank you so much this shit makes way more sense now
Such a big help!
Awesome vid, thank so much for the help!!!
HUGE HELP THXX!
My chem professor isn’t so helpful like you
I still have one question, what should you do if you had to round 773.87 down to 3 significant figures? Would you leave the decimal at the end or should you just leave it off?
you would write 774.00 because your question has 5 sig figs and when u round it, it should also have the same # of sig figs
Yeah but you have to round it to 3 sig figs

@@taylormurphy7740 thank you
thanks..
thanks 🥺🥺
My mom was watching this as well and thought she could copy and paste the words in this vid into notes 🤦🏼♂️ 🤣🤣
rounding 17.846239 to17.84, but there is 6 so we will give 1 to 4 and then it will be 17.85 so when it rounds it will be 17.9
this helped a lot but the lip smacks triggered me😂
Correct me if I’m wrong but shouldn’t the last question be 0.0560? You can’t turn 0.0562 into 0.056
0.056 and 0.0560 are the same number, just 0.0560 has an extra significant digit.
