Calculate the molar mass of air
Molar mass is a physical property defined as the mass of a given substance divided by its amount of substance, so it is a weight of one mole of substance. Molar mass is defined from the ideal gas law (Equation Mendeleev-Clapeyron): where - gas pressure, - molar volume, - mass of gas, - molar mass, - universal gas constant, - absolute temperature
