Molar and molecular weight of CMgO3

• Molecular formula: CMgO3 or MgCO3
• Relative molecular weight of CMgO3: 84.3139
• Molar mass of CMgO3: 84.3139 g/mol (0.08431 kg/mol)

Calculation of the relative molecular and molar mass of CMgO3

• Mr[CMgO3] = Ar[C] + Ar[Mg] + Ar[O] * 3 = 12.0107 + 24.305 + 15.9994 * 3 = 84.3139
• Molar mass (kg/mol) = Mr[CMgO3] : 1000 = 84.3139 : 1000 = 0.08431 kg/mol

CMgO3: percent composition by element

• Carbon (C) = 12.0107 : 84.3139 * 100 = 14.245 %
• Magnesium (Mg) = 24.305 : 84.3139 * 100 = 28.827 %
• Oxygen (O) = 47.9982 : 84.3139 * 100 = 56.928 %
