Molar mass - Wikipedia

In chemistry, the molar mass (M) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of said compound. The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes. Most commonly, the molar mass is computed from the standard atomic weights and is thus a terrestria… WebThe number of sodium atoms present = 1. The number of chlorine atoms present = 1. Mass of a sodium atom = 989770 amu. Mass of an oxygen atom = 45 amu. Therefore the molecular weight of H 2 O = (1x 99 amu) + (1 x 35.45 amu) = 58.44 amu.
