Molar and molecular weight of Ca3P2

• Relative molecular weight of Ca3P2: 182.181524
• Molar mass of Ca3P2: 182.181524 g/mol (0.18218 kg/mol)

Calculation of the relative molecular and molar mass of Ca3P2

• Mr[Ca3P2] = Ar[Ca] * 3 + Ar[P] * 2 = 40.078 * 3 + 30.973762 * 2 = 182.181524
• Molar mass (kg/mol) = Mr[Ca3P2] : 1000 = 182.181524 : 1000 = 0.18218 kg/mol

Ca3P2: percent composition by element

• Calcium (Ca) = 120.234 : 182.181524 * 100 = 65.997 %
• Phosphorus (P) = 61.947524 : 182.181524 * 100 = 34.003 %
