Molar and molecular weight of Sr(NO3)2

• Molecular formula: Sr(NO3)2 or N2O6Sr
• Relative molecular weight of Sr(NO3)2: 211.6298
• Molar mass of Sr(NO3)2: 211.6298 g/mol (0.21163 kg/mol)

Calculation of the relative molecular and molar mass of Sr(NO3)2

• Mr[Sr(NO3)2] = Ar[N] * 2 + Ar[O] * 6 + Ar[Sr] = 14.0067 * 2 + 15.9994 * 6 + 87.62 = 211.6298
• Molar mass (kg/mol) = Mr[Sr(NO3)2] : 1000 = 211.6298 : 1000 = 0.21163 kg/mol

Sr(NO3)2: percent composition by element

• Nitrogen (N) = 28.0134 : 211.6298 * 100 = 13.237 %
• Oxygen (O) = 95.9964 : 211.6298 * 100 = 45.361 %
• Strontium (Sr) = 87.62 : 211.6298 * 100 = 41.402 %
