How do I convert grams to liters in a chemical equation???

Question

aaronq · Answer

Assuming it's a gas, convert the mass to moles, the use PV=nRT

anonymous · Answer

Okay, how do I convert mass to moles?

aaronq · Answer

$\sf moles=\dfrac{mass}{Molar~mass}$

anonymous · Answer

Oh, okay. So what is PV=nRT?

palindromeman · Answer

Pressure x Volume = Number of moles x Gas Constant x Temperature
(PV)                                    (n)                       (R)                       (T)

The gas constant depends on the units used for volume, pressure, and temperature.

^is right. It's called the Ideal Gas law. see here for more info on each of the variables http://www.chemguide.co.uk/physical/kt/idealgases.html

anonymous · Answer

Our teacher never said anything about that formula. It's not even in the book. ?

aaronq · Answer

hmm, can you post the question itself?

maybe you just have to use the density
