Molar and molecular weight of C6CrO6

• Molecular formula: C6CrO6 or Cr(CO)6
• Relative molecular weight of C6CrO6: 220.0567
• Molar mass of C6CrO6: 220.0567 g/mol (0.22006 kg/mol)

Calculation of the relative molecular and molar mass of C6CrO6

• Mr[C6CrO6] = Ar[C] * 6 + Ar[Cr] + Ar[O] * 6 = 12.0107 * 6 + 51.9961 + 15.9994 * 6 = 220.0567
• Molar mass (kg/mol) = Mr[C6CrO6] : 1000 = 220.0567 : 1000 = 0.22006 kg/mol
