Molar and molecular weight of Cr(CO)6

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

Calculation of the relative molecular and molar mass of Cr(CO)6

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

Cr(CO)6: percent composition by element

• Carbon (C) = 72.0642 : 220.0567 * 100 = 32.748 %
• Chromium (Cr) = 51.9961 : 220.0567 * 100 = 23.629 %
• Oxygen (O) = 95.9964 : 220.0567 * 100 = 43.623 %
