Molar and molecular weight of BaCO3

• Molecular formula: BaCO3 or CBaO3
• Relative molecular weight of BaCO3: 197.3359
• Molar mass of BaCO3: 197.3359 g/mol (0.19734 kg/mol)

Calculation of the relative molecular and molar mass of BaCO3

• Mr[BaCO3] = Ar[C] + Ar[Ba] + Ar[O] * 3 = 12.0107 + 137.327 + 15.9994 * 3 = 197.3359
• Molar mass (kg/mol) = Mr[BaCO3] : 1000 = 197.3359 : 1000 = 0.19734 kg/mol

BaCO3: percent composition by element

• Carbon (C) = 12.0107 : 197.3359 * 100 = 6.086 %
• Barium (Ba) = 137.327 : 197.3359 * 100 = 69.59 %
• Oxygen (O) = 47.9982 : 197.3359 * 100 = 24.323 %
