• Relative molecular weight of C20H15P: 286.306862
• Molar mass of C20H15P: 286.306862 g/mol (0.28631 kg/mol)

Calculation of the relative molecular and molar mass of C20H15P

• Mr[C20H15P] = Ar[C] * 20 + Ar[H] * 15 + Ar[P] = 12.0107 * 20 + 1.00794 * 15 + 30.973762 = 286.306862
• Molar mass (kg/mol) = Mr[C20H15P] : 1000 = 286.306862 : 1000 = 0.28631 kg/mol
