- Mr[C2H7AsO2] = Ar[C] * 2 + Ar[H] * 7 + Ar[As] + Ar[O] * 2 = 12.0107 * 2 + 1.00794 * 7 + 74.9216 + 15.9994 * 2 = 137.99738
- Molar mass (kg/mol) = Mr[C2H7AsO2] : 1000 = 137.99738 : 1000 = 0.138 kg/mol
- Carbon (C) = 24.0214 : 137.99738 * 100 = 17.407 %
- Hydrogen (H) = 7.05558 : 137.99738 * 100 = 5.113 %
- Arsenic (As) = 74.9216 : 137.99738 * 100 = 54.292 %
- Oxygen (O) = 31.9988 : 137.99738 * 100 = 23.188 %
