Molar and molecular weight of C2CaO4

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

Calculation of the relative molecular and molar mass of C2CaO4

• Mr[C2CaO4] = Ar[C] * 2 + Ar[Ca] + Ar[O] * 4 = 12.0107 * 2 + 40.078 + 15.9994 * 4 = 128.097
• Molar mass (kg/mol) = Mr[C2CaO4] : 1000 = 128.097 : 1000 = 0.1281 kg/mol

C2CaO4: 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 %
