Molar and molecular weight of PbSiO3

• Molecular formula: PbSiO3 or O3PbSi
• Relative molecular weight of PbSiO3: 283.2837
• Molar mass of PbSiO3: 283.2837 g/mol (0.28328 kg/mol)

Calculation of the relative molecular and molar mass of PbSiO3

• Mr[PbSiO3] = Ar[O] * 3 + Ar[Pb] + Ar[Si] = 15.9994 * 3 + 207.2 + 28.0855 = 283.2837
• Molar mass (kg/mol) = Mr[PbSiO3] : 1000 = 283.2837 : 1000 = 0.28328 kg/mol

PbSiO3: percent composition by element

• Oxygen (O) = 47.9982 : 283.2837 * 100 = 16.944 %
• Lead (Pb) = 207.2 : 283.2837 * 100 = 73.142 %
• Silicon (Si) = 28.0855 : 283.2837 * 100 = 9.914 %
