Molar and molecular weight of Co(ClO4)2

• Relative molecular weight of Co(ClO4)2: 257.834395
• Molar mass of Co(ClO4)2: 257.834395 g/mol (0.25783 kg/mol)

Calculation of the relative molecular and molar mass of Co(ClO4)2

• Mr[Co(ClO4)2] = Ar[Co] + Ar[Cl] * 2 + Ar[O] * 8 = 58.933195 + 35.453 * 2 + 15.9994 * 8 = 257.834395
• Molar mass (kg/mol) = Mr[Co(ClO4)2] : 1000 = 257.834395 : 1000 = 0.25783 kg/mol
