Difference between molecular mass and molar mass
Molecular mass | Molar mass |
---|---|
The molecular mass is the sum of mass of all the atoms present in a molecule. | Molar mass is the mass of 1 mole of molecules i.e. mass of 6.022×1023 molecules. |
Expressed in amu (atomic mass unit) | Expressed in g/mol |
Example: Mass of 1 H2O molecule is 18 amu | Example: Mass of 6.022×1023 molecules of H2O is 18 g/mol |
