Around `20%` surface sites have adsorbed `N_(2)`. On heating `N_(2)` gas evolved form sites and were collected at 0.001 atm and 298 K in a container of volume `2.46cm^(3)` the density of surface sites is `6.023xx10^(14)cm^(-2)` and surface area is `1000cm^(2)` find out the number of surface sites occupied per molecule of `N_(2)`.

Explanation

No. of surface sites per molecule of `N_2 = (" no. of surface sites used to adsorb "N_2 "on a surface area of" 1000 cm^2)/(" total no. of adsorbed molecules ")`
