Molar and molecular weight of In(NO3)3

• Molecular formula: In(NO3)3 or InN3O9
• Relative molecular weight of In(NO3)3: 300.8327
• Molar mass of In(NO3)3: 300.8327 g/mol (0.30083 kg/mol)

Calculation of the relative molecular and molar mass of In(NO3)3

• Mr[In(NO3)3] = Ar[In] + Ar[N] * 3 + Ar[O] * 9 = 114.818 + 14.0067 * 3 + 15.9994 * 9 = 300.8327
• Molar mass (kg/mol) = Mr[In(NO3)3] : 1000 = 300.8327 : 1000 = 0.30083 kg/mol

In(NO3)3: percent composition by element

• Indium (In) = 114.818 : 300.8327 * 100 = 38.167 %
• Nitrogen (N) = 42.0201 : 300.8327 * 100 = 13.968 %
• Oxygen (O) = 143.9946 : 300.8327 * 100 = 47.865 %
