How would you convert volume to moles?

Question

anonymous · Answer

You can't directly convert volume to moles. A mole of something is 6.022 x 10^23 of something. But there is a relationship between moles of a substance and volume in the equation:$$PV = nRT$$ Pressure times volume is equal to the product of the moles of a substance, the gas constant and the temperature. As the number of moles n, increases, so does the volume.

like Liters to mol ?

anonymous · Answer

Liter are a measure of space, moles are a measure of quantity. Are you working on gas problems? Do you have an example of what you're trying to do?

jfraser · Answer

or is it an aqueous solution, with a concentration? or is it a pure liquid, with a volume and a density?

be more specific

if my memory serves me write  doesn't 22.4 liters of a gas at standard temperature and pressure contain one mole of  gas?

cwrw238 · Answer

its a while since i studied chemistry...

jfraser · Answer

@cwrw238 it does, but unless the OP is asking about a gas, the question is impossible to answer.

cwrw238 · Answer

yes i agree

anonymous · Answer

in the general case,

Volume x density / molecular mass = moles

for the specific case of an ideal gas when you know pressure and temperature...

PV=nRT
n = PV / RT
