Molar and molecular weight of Ba(PO3)2

• Relative molecular weight of Ba(PO3)2: 295.270924
• Molar mass of Ba(PO3)2: 295.270924 g/mol (0.29527 kg/mol)

Calculation of the relative molecular and molar mass of Ba(PO3)2

• Mr[Ba(PO3)2] = Ar[Ba] + Ar[P] * 2 + Ar[O] * 6 = 137.327 + 30.973762 * 2 + 15.9994 * 6 = 295.270924
• Molar mass (kg/mol) = Mr[Ba(PO3)2] : 1000 = 295.270924 : 1000 = 0.29527 kg/mol
