liters to grams??

[GameGURU]

If I want to go from Liters (Volume) of something, to Grams, do I have to go to Moles in between?

If I do that, I have to know the molar mass of the element I am dealing with right?

or look up its density

if its water@STP its 1 to 1

Oh boy, don't even get me started on moles. Sooooo confusing!!! I do have some notes if you'd like me to show you.

Well I have a chem test tomarrow and this is the only thing I dont understand.

How about this :

You have 88.0g of NO2 , what is the Volume in Liters?

So what I did was:

88.0g NO2 X 22.4L (liters in a mole [the given])
_______________

46.005g (molar mass) X 1

King Henry Died Drinking Chocolate Milk...... K H D D C M .... kilogram, hectagram (or sumtin), Decagram....... Decimeter, Centimeter, Milimeter........ aha i went from weight to distance. whatever i remembered that from 5th grade.

hey, its been like 24 years since Ihad chem in highschool, off the top of my head if I remember right, isnt 1 mole=6.023x10^23 molecules of a molecule?Or im I nuts and thats just a useless number to me at this point?

Never had to do more than biology in highschool

you guys are too schmart fer me

you're right, but there is alot more to these equations than that lol

 

[horndude]

well cool, guess I havent killed ALL my brain cells at this point

hmmm, ok so doesnt the periodic table have a listing of mole weights er something, that and a quantity and your good to go?

I know, its complicated, wait till college it gets worse, I thought math basically stopped at calculus 2, nope not even close, I did ok in chem and physics but when we started writing equations to describe the operation of complex circuits like stereos I started having problems
