Molar and molecular weight of MnCO3

• Molecular formula: MnCO3 or CMnO3
• Relative molecular weight of MnCO3: 114.946945
• Molar mass of MnCO3: 114.946945 g/mol (0.11495 kg/mol)

Calculation of the relative molecular and molar mass of MnCO3

• Mr[MnCO3] = Ar[C] + Ar[Mn] + Ar[O] * 3 = 12.0107 + 54.938045 + 15.9994 * 3 = 114.946945
• Molar mass (kg/mol) = Mr[MnCO3] : 1000 = 114.946945 : 1000 = 0.11495 kg/mol

MnCO3: percent composition by element

• Carbon (C) = 12.0107 : 114.946945 * 100 = 10.449 %
• Manganese (Mn) = 54.938045 : 114.946945 * 100 = 47.794 %
• Oxygen (O) = 47.9982 : 114.946945 * 100 = 41.757 %
