A sample of 16 g charcoal was brought into contact with CH gas contained in a vessel of 1 litre at `27^@C`. The. pressure of gas was found to fall from 760 to 608 torr. The density of charcoal sample is `1.6 g//cm^3`. What is the volume of the `CH_4` gas adsorbed per gram of the adsorbentat 608 torr and `27^@C` ?

A

125 mL/g

B

16.25 mL/g

C

26 mL/g

D

82.5 mL/g

Text Solution

Verified by Experts

The correct Answer is:
B
Final volume of gas at 608 torr pressure `V_(2)=(P_(1)V_(1))/(P_(2))=(760xx1)/(608) rarr 1.25 or V_(2) =1250` mL
Difference of volume is due to adsorption of gas by charcaol
volume of the gas adsorbd per gram of characoal =`(260)/(16) =16.25` mL / g at 608torr and `27^(@)` C
