Molar and molecular weight of CO3

• Relative molecular weight of CO3: 60.0089
• Molar mass of CO3: 60.0089 g/mol (0.06001 kg/mol)

Calculation of the relative molecular and molar mass of CO3

• Mr[CO3] = Ar[C] + Ar[O] * 3 = 12.0107 + 15.9994 * 3 = 60.0089
• Molar mass (kg/mol) = Mr[CO3] : 1000 = 60.0089 : 1000 = 0.06001 kg/mol

CO3: percent composition by element

• Carbon (C) = 12.0107 : 60.0089 * 100 = 20.015 %
• Oxygen (O) = 47.9982 : 60.0089 * 100 = 79.985 %
