WebDec 8, 2015 · A mole is 6.02 ⋅ 1023 (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses. Explanation: The amount of molecules of any substance to make 1 mole is constant. However, due to differing atomic masses, different molecules will have different molar masses. WebFor example, the molar mass of water (H2O) is 18 g/mol because the atomic mass of hydrogen (H) is 1 g/mol and the atomic mass of oxygen (O) is 16 g/mol. Molar mass is an important concept in chemistry because it allows for the conversion of mass to moles and vice versa. This is particularly useful when conducting chemical reactions.
