Molar and molecular weight of PbSO4

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

Calculation of the relative molecular and molar mass of PbSO4

• Mr[PbSO4] = Ar[O] * 4 + Ar[Pb] + Ar[S] = 15.9994 * 4 + 207.2 + 32.065 = 303.2626
• Molar mass (kg/mol) = Mr[PbSO4] : 1000 = 303.2626 : 1000 = 0.30326 kg/mol

PbSO4: 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 %
