Molar and molecular weight of Cu(NO3)2

• Molecular formula: Cu(NO3)2 or CuN2O6
• Relative molecular weight of Cu(NO3)2: 187.5558
• Molar mass of Cu(NO3)2: 187.5558 g/mol (0.18756 kg/mol)

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

• Mr[Cu(NO3)2] = Ar[Cu] + Ar[N] * 2 + Ar[O] * 6 = 63.546 + 14.0067 * 2 + 15.9994 * 6 = 187.5558
• Molar mass (kg/mol) = Mr[Cu(NO3)2] : 1000 = 187.5558 : 1000 = 0.18756 kg/mol
