Molar and molecular weight of H2Mg

• Molecular formula: H2Mg or MgH2
• Relative molecular weight of H2Mg: 26.32088
• Molar mass of H2Mg: 26.32088 g/mol (0.02632 kg/mol)

Calculation of the relative molecular and molar mass of H2Mg

• Mr[H2Mg] = Ar[H] * 2 + Ar[Mg] = 1.00794 * 2 + 24.305 = 26.32088
• Molar mass (kg/mol) = Mr[H2Mg] : 1000 = 26.32088 : 1000 = 0.02632 kg/mol

H2Mg: percent composition by element

• Hydrogen (H) = 2.01588 : 26.32088 * 100 = 7.659 %
• Magnesium (Mg) = 24.305 : 26.32088 * 100 = 92.341 %
