Molar and molecular weight of C2Ca

• Molecular formula: C2Ca or CaC2
• Relative molecular weight of C2Ca: 64.0994
• Molar mass of C2Ca: 64.0994 g/mol (0.0641 kg/mol)

Calculation of the relative molecular and molar mass of C2Ca

• Mr[C2Ca] = Ar[C] * 2 + Ar[Ca] = 12.0107 * 2 + 40.078 = 64.0994
• Molar mass (kg/mol) = Mr[C2Ca] : 1000 = 64.0994 : 1000 = 0.0641 kg/mol

C2Ca: percent composition by element

• Carbon (C) = 24.0214 : 64.0994 * 100 = 37.475 %
• Calcium (Ca) = 40.078 : 64.0994 * 100 = 62.525 %
