The volume of nitrogen gas at 0^(@)C and...

The volume of nitrogen gas at `0^(@)C` and 1.013 bar required to cover a sample of silica gel with unimolecular layer is `129 cm^(3) g^(–1)` of gel. Calculate the surface area per gram of the gel if each nitrogen molecule occupies `16.2 xx 10^(–20) m^(2)`.

Text Solution

Verified by Experts

`568m^(2)g^(-1)`
`PV=nRT`
`1.013 xx 0.129 = n xx 0.0821 xx 273`
`n=0.00583` mol
Area occupied
`=0.00583 xx 6.023 xx 10^(23) xx 16.2 xx 10^(-20)`
