My chem teacher took 3 millennia to teach us this and I still couldn't understand it until I watched this video thank you so much

why cant people explain it like this!!! i love this guy!!!! it only took him 7 minutes and my teacher took 3 lecture hours and i didn't know what was going on!

THANK YOU! This really helped! I was having trouble with limiting reactants. Thank you! I will subscribe!

Why did you skip the math portion of this?!

what did you put in the calculator to get that answer if everything cancelled out

You just saved my life

don't understand how you got to 44.

the formula of propane is C3H8, this means that there are 3 carbon atoms and and 8 hydrogen atoms, because of this you take 3 times the relative atomic mass of carbon which is 3 x 12(equals to 36) and then take 4 times the relative atomic mass of hydrogen which is 1 x 8(equals to 8) and then add them together because the formula is C3H8, so it's 36 plus 8 then you will get 44 :)

How did you get 1.4 g. Like what did you put in the calculator

do you know how amazing you are? you're voice just makes things simple.

Helped out so much!!!

In 4:47 why do you only multiply 16.00 by two and not with the 5 in the coefficient?

saved me from my test!! ily

Wtf...how did you get 32 and 44? I'm so confused.

its molar mass. o on periodic table has an atomic mass of 16, so o2 will be 32. c-12. so c3 will be 36. add that to 8*h(1), and you get 44.

Hi please can you explain what you put into a calculator to get 1.4 g of propane. I don't understand what calculation you've done

do balancing first

***** this might help us:)

u r explanation is nice but its not so clear

that doesn't help at all because you don't explain how you came up with the conversion factors.

you move the paper to much, even the slightest little move. otherwise great video.

Very heavy breathing. Very distracting. I'm sure there was good content, but I couldn't get through the end with the huffing and puffing
