In freshman chemistry, the relationship between moles and mass is introduced: n%3D MW where n= number of moles of a substance, m= mass of the substance, and MW = molecular weight (molar mass) of the substance. %3D The ideal gas law gives us a relationship between volume, temperature, pressure, and the number of moles of an ideal gas in a container as follows.

In freshman chemistry, the relationship between moles and mass is
introduced:
72
MW
where
n= number of moles of a substance,
m= mass of the substance, and
MW = molecular weight (molar mass) of the substance.

The ideal gas law gives us a relationship between volume, temperature,
pressure, and the number of moles of an ideal gas in a container as follows.
PV= nRT
where
P is the pressure,
V is the volume,
Tis the absolute temperature,
N is the number of moles of gas, and
R= 0.0821 L.atm/(mol K).
