At 1 atm and 273 K the volume of nitrogen gas required to cover a sample of silica gel, assuming Langmuir monolayer adsorption , is found to be `1.30 cm^(3)g^(-1)` of the gel. The area occupoied by a nitrogen molecule os `0.16nm^(2)`. Find out the no. of surface sites occupied per molecule of `H_(2)`.
The volume of nitrogen gas Vm (at STP) reqired to cover a sample of silica gel with a monomolecular layer is 129cm^(3)g^(-1) of gel. Calculate the surface area per gram of the gel if each nitrogen molecule occupies 16.23xx10^(-20)m^(2) .
The volume of nitrogen gas Um (measured at STP) required to cover a sample of silica get with a mono-molecular 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).
1.30 cm^(3) of N_(2) gas at STP is adsorbed per gram of silica gel. The area occupied by nitrogen molecule is 0.16 nm^(2) . What is the surface area per gram of silica gel ? (N_(A)=6.023xx10^(23))
