Molar and molecular weight of H2Ca

• Molecular formula: H2Ca or CaH2
• Relative molecular weight of H2Ca: 42.09388
• Molar mass of H2Ca: 42.09388 g/mol (0.04209 kg/mol)

Calculation of the relative molecular and molar mass of H2Ca

• Mr[H2Ca] = Ar[H] * 2 + Ar[Ca] = 1.00794 * 2 + 40.078 = 42.09388
• Molar mass (kg/mol) = Mr[H2Ca] : 1000 = 42.09388 : 1000 = 0.04209 kg/mol

H2Ca: percent composition by element

• Hydrogen (H) = 2.01588 : 42.09388 * 100 = 4.789 %
• Calcium (Ca) = 40.078 : 42.09388 * 100 = 95.211 %
