Molar and molecular weight of Sr(NO2)2

• Molecular formula: Sr(NO2)2 or N2O4Sr
• Relative molecular weight of Sr(NO2)2: 179.631
• Molar mass of Sr(NO2)2: 179.631 g/mol (0.17963 kg/mol)

Calculation of the relative molecular and molar mass of Sr(NO2)2

• Mr[Sr(NO2)2] = Ar[N] * 2 + Ar[O] * 4 + Ar[Sr] = 14.0067 * 2 + 15.9994 * 4 + 87.62 = 179.631
• Molar mass (kg/mol) = Mr[Sr(NO2)2] : 1000 = 179.631 : 1000 = 0.17963 kg/mol

Sr(NO2)2: percent composition by element

• Nitrogen (N) = 28.0134 : 179.631 * 100 = 15.595 %
• Oxygen (O) = 63.9976 : 179.631 * 100 = 35.627 %
• Strontium (Sr) = 87.62 : 179.631 * 100 = 48.778 %
