Two moles of an ideal monoatomic gas at$5$bar and$\text{300}\text{K}$are expanded irreversibly up to a final pressure of$\text{1}$bar and$\text{240}\text{K}$against an external pressure of$\text{0}\text{.5}$bar. The work done by the gas is$-\text{xR}$. The value of '$\text{x}$' is
(Here '$\text{R}$' is gas constant)
