The pressure of the gas was found to decrease from 720 to 480 m. When 5g of sample of activated charcoal was kept in a flask of one litre capacity maintained at 27^(@)C . If the density of charcoal at 1.25 gm//mL. The volume of gas adsorbed per gm of charcoal at 480 mm of Hg is

Answer»

`80.03 mL`
`32.20 mL`
`100.08mL`
None of these

Solution :`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`
