Molar and molecular weight of SnO2

• Molecular formula: SnO2 or O2Sn
• Relative molecular weight of SnO2: 150.7088
• Molar mass of SnO2: 150.7088 g/mol (0.15071 kg/mol)

Calculation of the relative molecular and molar mass of SnO2

• Mr[SnO2] = Ar[O] * 2 + Ar[Sn] = 15.9994 * 2 + 118.71 = 150.7088
• Molar mass (kg/mol) = Mr[SnO2] : 1000 = 150.7088 : 1000 = 0.15071 kg/mol

SnO2: percent composition by element

• Oxygen (O) = 31.9988 : 150.7088 * 100 = 21.232 %
• Tin (Sn) = 118.71 : 150.7088 * 100 = 78.768 %
