Molar and molecular weight of CaC2O4

• Molecular formula: CaC2O4 or C2CaO4
• Relative molecular weight of CaC2O4: 128.097
• Molar mass of CaC2O4: 128.097 g/mol (0.1281 kg/mol)

Calculation of the relative molecular and molar mass of CaC2O4

• Mr[CaC2O4] = Ar[C] * 2 + Ar[Ca] + Ar[O] * 4 = 12.0107 * 2 + 40.078 + 15.9994 * 4 = 128.097
• Molar mass (kg/mol) = Mr[CaC2O4] : 1000 = 128.097 : 1000 = 0.1281 kg/mol

CaC2O4: percent composition by element

• Carbon (C) = 24.0214 : 128.097 * 100 = 18.753 %
• Calcium (Ca) = 40.078 : 128.097 * 100 = 31.287 %
• Oxygen (O) = 63.9976 : 128.097 * 100 = 49.96 %
