Calculation of the relative molecular and molar mass of C6HCl5O

• Mr[C6HCl5O] = Ar[C] * 6 + Ar[H] + Ar[Cl] * 5 + Ar[O] = 12.0107 * 6 + 1.00794 + 35.453 * 5 + 15.9994 = 266.33654
• Molar mass (kg/mol) = Mr[C6HCl5O] : 1000 = 266.33654 : 1000 = 0.26634 kg/mol

C6HCl5O: percent composition by element

• Carbon (C) = 72.0642 : 266.33654 * 100 = 27.058 %
• Hydrogen (H) = 1.00794 : 266.33654 * 100 = 0.378 %
• Chlorine (Cl) = 177.265 : 266.33654 * 100 = 66.557 %
• Oxygen (O) = 15.9994 : 266.33654 * 100 = 6.007 %
