• Molecular formula: SO2(NCO)2 or C2N2O4S
• Relative molecular weight of SO2(NCO)2: 148.0974
• Molar mass of SO2(NCO)2: 148.0974 g/mol (0.1481 kg/mol)

Calculation of the relative molecular and molar mass of SO2(NCO)2

• Mr[SO2(NCO)2] = Ar[C] * 2 + Ar[N] * 2 + Ar[O] * 4 + Ar[S] = 12.0107 * 2 + 14.0067 * 2 + 15.9994 * 4 + 32.065 = 148.0974
• Molar mass (kg/mol) = Mr[SO2(NCO)2] : 1000 = 148.0974 : 1000 = 0.1481 kg/mol

SO2(NCO)2: percent composition by element

• Carbon (C) = 24.0214 : 148.0974 * 100 = 16.22 %
• Nitrogen (N) = 28.0134 : 148.0974 * 100 = 18.916 %
• Oxygen (O) = 63.9976 : 148.0974 * 100 = 43.213 %
• Sulfur (S) = 32.065 : 148.0974 * 100 = 21.651 %
