Molar and molecular weight of SrCO3

• Molecular formula: SrCO3 or CO3Sr
• Relative molecular weight of SrCO3: 147.6289
• Molar mass of SrCO3: 147.6289 g/mol (0.14763 kg/mol)

Calculation of the relative molecular and molar mass of SrCO3

• Mr[SrCO3] = Ar[C] + Ar[O] * 3 + Ar[Sr] = 12.0107 + 15.9994 * 3 + 87.62 = 147.6289
• Molar mass (kg/mol) = Mr[SrCO3] : 1000 = 147.6289 : 1000 = 0.14763 kg/mol

SrCO3: percent composition by element

• Carbon (C) = 12.0107 : 147.6289 * 100 = 8.136 %
• Oxygen (O) = 47.9982 : 147.6289 * 100 = 32.513 %
• Strontium (Sr) = 87.62 : 147.6289 * 100 = 59.352 %
