A mixture of 10 ml `CH_(4), C_(2)H_(4) and C_(2)H_(2)` has a vapour density of 11.3. When 30 ml of oxygen are sparked together over aqueous KOH, the volume contracts to 5.5 ml and then disappears when pyrogallol is introduced. If volumes are measured in the same conditions of pressure temperatre and humidity, calculate the composition of the original mixture.

Text Solution

Verified by Experts

`CH_(4)=4 ml, C_(2)H_(4)=3 ml, C_(2)H_(2)=3 ml`
