Molar Mass

Molar Mass

Molar mass is defined as the mass of one mole of a substance. The molar mass of a compound is equal to the sum of the relative atomic masses of its constituents expressed in g mol^-1.

Examples:

·       relative atomic mass of one hydrogen atom = 1.008 u

·       molar mass  of hydrogen atom = 1.008 g mol^-1

·        relative  molecular  mass  of  glucose = 180 u

·        molar mass of glucose = 180 g mol^-1
