Molar and molecular weight of CaC2

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

Calculation of the relative molecular and molar mass of CaC2

• Mr[CaC2] = Ar[C] * 2 + Ar[Ca] = 12.0107 * 2 + 40.078 = 64.0994
• Molar mass (kg/mol) = Mr[CaC2] : 1000 = 64.0994 : 1000 = 0.0641 kg/mol

CaC2: percent composition by element

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