Usually, this formula is used when... Weband number of moles by combining the above gas laws to generate the ideal gas law; PV = nRT. R is called the universal gas constant or ideal gas constant and is commonly written as 0.0821 L atm/mole K. Since n = mass/molecular weight, we can substitute into the ideal gas equation and use the relationship to determine the molecular weight of a gas.
