Finding molar mass starts with units of grams per mole (g/mol) when calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance the formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
You have to keep your eyes open particularly when reading old papers and books today it is always gram mol ( or mole sometimes) then the molar mass of methane. The molar volume is directly proportional to molar mass and inversely proportional to density the formula of molar volume is expressed as where v m is the volume of the substance.
