Molar and molecular weight of P

• Relative molecular weight of P: 30.973762
• Molar mass of P: 30.973762 g/mol (0.03097 kg/mol)

Calculation of the relative molecular and molar mass of P

• Mr[P] = Ar[P] = 30.973762 = 30.973762
• Molar mass (kg/mol) = Mr[P] : 1000 = 30.973762 : 1000 = 0.03097 kg/mol
