Molar and molecular weight of CCaO3

• Molecular formula: CCaO3 or CaCO3
• Relative molecular weight of CCaO3: 100.0869
• Molar mass of CCaO3: 100.0869 g/mol (0.10009 kg/mol)

Calculation of the relative molecular and molar mass of CCaO3

• Mr[CCaO3] = Ar[C] + Ar[Ca] + Ar[O] * 3 = 12.0107 + 40.078 + 15.9994 * 3 = 100.0869
• Molar mass (kg/mol) = Mr[CCaO3] : 1000 = 100.0869 : 1000 = 0.10009 kg/mol

CCaO3: percent composition by element

• Carbon (C) = 12.0107 : 100.0869 * 100 = 12 %
• Calcium (Ca) = 40.078 : 100.0869 * 100 = 40.043 %
• Oxygen (O) = 47.9982 : 100.0869 * 100 = 47.957 %
