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.
· 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
