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)`.
A. `5.568 m^(2)g^(-1)`
B. `3.34 m^(2) g^(-1)`
C. `1.6 m^(2) g^(-1)`
D. none of these
