Answer» Correct Answer - 3 `V_(2)=(P_(1)V_(1))/(P_(2))=(720xx1000)/(480)=1500ml` Volume of gas in the flask `=1000-` volume of charcoal `1000-(5)/(1.25)=996ml` Total volume of gas adsorbe by charcoal `=1500-996=504ml` Volume of gas adsorbe by per gram of charcoal `=(504)/(5)=100.08ml` `V_(2)=(P_(1)V_(1))/(P_(2))=(720xx1000)/(480)=1500ml`
