Molar and molecular weight of Co(NO3)3

• Relative molecular weight of Co(NO3)3: 244.947895
• Molar mass of Co(NO3)3: 244.947895 g/mol (0.24495 kg/mol)

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

• Mr[Co(NO3)3] = Ar[Co] + Ar[N] * 3 + Ar[O] * 9 = 58.933195 + 14.0067 * 3 + 15.9994 * 9 = 244.947895
• Molar mass (kg/mol) = Mr[Co(NO3)3] : 1000 = 244.947895 : 1000 = 0.24495 kg/mol

Co(NO3)3: percent composition by element
