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

A

`80.03 mL`

B

`32.20 mL`

C

`100.08 mL`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(2)=(P_(1)V_(1))/(P_(2))=(720xx1000)/(480)=1500 ml`
Volume of gas in the flask `=1000- "volume of charcoal"=1000-5/1.25=996 ml`
Total volume of gas adsorbe by charcoal `=1500-996=504 ml`
Volume of gas adsorbe by per gram of charcoal `=504/5=100.08 ml`

Adsorption is the presence of excess concentration of any particular component at the surface of liquid a solid phase as compared to bulk.This is due to presence of residual forces at the surface of body.In the adsorption of hydrogen gas over a sample of charcoal, 1.12cm^3 of H_2(g) measured over S.T.P was found to absorb per gram of charcoal.Consider only monolayer adsorption.Density of H_2 is 0.07gm/cc. In another experiment same 1 gm charcoal adsorbs 100 ml of 0.5M CH_3COOH to form monolayer and thereby the molarity of CH_3COOH reduces to 0.49. ((3xx47.43)/(4pi))^(1//3)=2.24 (2.24)^2=5 Surface area of charcoal adsorbed by each molecule of (acetic soda) is-
