Simplified Method for Mole Conversions

[PresleyPoison15]

what happens if you know what you have for liters and you want to convert to molecules?

[eplybon]

@PresleyPoison15 There are 22.4 L in one mole. Use that information to find out how many moles you have, then you can convert to molecules.

Thank you! this made everything easier!

[TRISTEF13maniakz1]

this is understandable but still hard

[zverevavika]

I wish you were my teacher in real life!

[Xspy70]

Wow. This is so easy now. I hate how the teachers try to explain it "scientifically". I end up with pages full of crap and examples but not an idea of how it works. Thanks!

I have an urgent question, though! On the chart it says to divide by avogadros number to get from atoms to moles, but how do you do that seeing as avogadro's number is scientific notation? Help please!

[eplybon]

@LeilaLilzMathy it's fairly simple to multiply and divide by numbers using scientific notation. The rule is if you are multiplying, you add the exponents and if you are dividing, you subract them. In this case, if you are dividing by Avogadro's number, you would take the exponent of the number on top and subtract 23 (the exponent in Avogadro's number). Example, 7.83 x 10^26 divided by 6.02 x 10^23 would be 7.83/6.02 = 1.30 x 10^3

Thank you for making this previously confusing subject very simple ... I appreciate what you have done for me ...

[Mrtinngwe]

you should show some questions solving then maybe i'll understand better.

Your audio is too quiet.

I am soooo great-full for your story!! The visual was extremely helpful, as was the story. Thank both you and your math-guy/hubby!! It made this really nice to get through the complexities and even shared with friends! LOL... Thanks again!

i have a question! i replayed the part on how to convert atoms into grams like ten times but i still am not getting one part

so first we divide atoms by the avogrando's # ( then you said something about going through moles?? thats were you lost me does that mean we have to do something with moles or not??) then after that confusing part we multiply by the molar mass right???

can you help me??

[eplybon]

@maria1239876 what that part is saying is that once you have divided by avagadro's number, you have the number of moles, so you are not done yet. You are correct - if you are wanting to go from atoms to grams, then you will divide by avagadro's number, then multiply by molar mass. Sorry for the confusion :)

thanks! it helped lots!

I used this to study for my exxam!

[eplybon]

akyma177 this could be because of the way you are entering your exponents. Can you tell me how you are doing this on your calculator?

[akyma177]

This helps so much! Thank you! I was practicing some problems and the answer is always in there but the decimal place always seems to be off unless i'm doing something wrong?

[quickadd1]

i agree with everyone else, this video and the chart makes sooo much more sense! i don't understand why professors need to make it so complicated!

[iKristina1980]

OK so I am in prechem at the uni. I read the pearsons text and barely any made sense. I googled and the same. Your chart made a TON of sense. Thanks for saving me from feeling like I need to withdraw.

[chingalingsmiles]

You are soooooooooooo awesome! this just helped me out soooo much!(:

[RICHLALA]

no i meant thanku to her husband for figurin out a way to help us kids in a visual way. i was thanking them both so u FAIL for lack of comprehension skils..

[RICHLALA]

OMG THANKU SO MUCH. You dont know how grateful I am for you putting up this video and thanku to Mr.Plybon too!.

[deniese95]

@RICHLALA

omg you FAIL. You spelt as Mr instead of Mrs

[Airshot06]

yeah this video was really helpful thank you!!! :)

[believescience]

The story part of this video wasnt vey helpful, but the chart that you made was a very big help
