Molar and molecular weight of O4PbS

• Molecular formula: O4PbS or PbSO4
• Relative molecular weight of O4PbS: 303.2626
• Molar mass of O4PbS: 303.2626 g/mol (0.30326 kg/mol)

Calculation of the relative molecular and molar mass of O4PbS

• Mr[O4PbS] = Ar[O] * 4 + Ar[Pb] + Ar[S] = 15.9994 * 4 + 207.2 + 32.065 = 303.2626
• Molar mass (kg/mol) = Mr[O4PbS] : 1000 = 303.2626 : 1000 = 0.30326 kg/mol

O4PbS: percent composition by element

• Oxygen (O) = 63.9976 : 303.2626 * 100 = 21.103 %
• Lead (Pb) = 207.2 : 303.2626 * 100 = 68.324 %
• Sulfur (S) = 32.065 : 303.2626 * 100 = 10.573 %
