• Molar mass of Mn(NO3)2: 178.947845 g/mol (0.17895 kg/mol)

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

• Mr[Mn(NO3)2] = Ar[Mn] + Ar[N] * 2 + Ar[O] * 6 = 54.938045 + 14.0067 * 2 + 15.9994 * 6 = 178.947845
• Molar mass (kg/mol) = Mr[Mn(NO3)2] : 1000 = 178.947845 : 1000 = 0.17895 kg/mol
