A mixture of $\displaystyle \mathrm{N}_2$ and Ar gases in a cylinder contains $\displaystyle 7$ g of $\displaystyle \mathrm{N}_2$ and $\displaystyle 8$ g of Ar . If the total pressure of the mixture of the gases in the cylinder is $\displaystyle 27$ bar, the partial pressure of $\displaystyle \mathrm{N}_2$ is : [Use atomic masses (in $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$ ) : $\displaystyle \mathrm{N}=14, \mathrm{Ar}=40$ ]
