Explanation:

If the pressure, volume, and temperature of a gas are known than molar amount can be determine.

Formula:

PV = nRT

P = pressure

V = volume

R = general gas constant

T = temperature

n = number of moles

Example:

V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K

n = PV/RT

n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K

n = 2 / 22.413 /mol

n = 0.09 mol
