AT STP the volume of nitrogen gas required to cover a sample of silica gel, assuming Langmuir monolayer adsorption, is found to be `1.3^30^1` of the gel. The area occupied by a nitrogen molecule is `0.1 0^2` What is the surface area per gram of silica gel? [Given `N_A =6 diamond ^2`]

A

`5.5^2 6^1`

B

`3.4^2 8^1`

C

`1.6^2 1^7`

D

None of these

Text Solution

Verified by Experts

Number of molecules per gram of `N_2` in monolayer
=`600^(23)
22,400
Cross-sectional area of a molecule =`10^15`
Area covered by molecules per gram =313113
\ surface area =`5.5^2 6`
