Molar mass

2014-07-02 Finding molar mass (also called molecular weight, molecular mass, and gram formula mass) is an essential skill in chemistry, especially for mole to gram conv Molar mass (M) is a physical property, defined as the mass of a given element or molecule per mole of that substance. Since a mole is defined as the amount of a substance and substances have different masses, each element or molecule will have a different molar mass. In chemistry, the molar mass of a chemical compound is defined as the mass of the sample chemical compound divided by the amount of the sample substance. The molar mass is measured in grams per mole (g/mol). In general, the molar mass is the ratio of the mass of the substance to the number of particles present in it.
