Molar and molecular weight of Ca(IO3)2

• Relative molecular weight of Ca(IO3)2: 389.88334
• Molar mass of Ca(IO3)2: 389.88334 g/mol (0.38988 kg/mol)

Calculation of the relative molecular and molar mass of Ca(IO3)2

• Mr[Ca(IO3)2] = Ar[Ca] + Ar[I] * 2 + Ar[O] * 6 = 40.078 + 126.90447 * 2 + 15.9994 * 6 = 389.88334
• Molar mass (kg/mol) = Mr[Ca(IO3)2] : 1000 = 389.88334 : 1000 = 0.38988 kg/mol
