A compound containing 4.07% Hydrogen, 24.27% Carbon & 71.67% Chlorine. Molecular Mass is 98.96g. What are it's emperial formula & molecular formula ?
Element | Percentage Ratio | Simple Ratio | Empirical Formula |
Carbon | 24.27/12 = 2.02 | 2.02/2.01 =1 | CH2Cl |
Hydrogen | 4.07/1 = 4.07 | 4.07/2.01 =2 |
|
Chlorine | 71.67/35.5 = 2.01 | 2.01/2.01 = 1 |
|
Empirical formula weight: CH2Cl = 12 + 1x2 + 35.5
= 49.5
Molecular formula ratio = 98.96/49.5 ≈ 2
Molecular formula = C2H4Cl2
