Molar and molecular weight of H2

• Relative molecular weight of H2: 2.01588
• Molar mass of H2: 2.01588 g/mol (0.00202 kg/mol)

Calculation of the relative molecular and molar mass of H2

• Mr[H2] = Ar[H] * 2 = 1.00794 * 2 = 2.01588
• Molar mass (kg/mol) = Mr[H2] : 1000 = 2.01588 : 1000 = 0.00202 kg/mol
