One mole of an ideal gas at $27 °\mathrm{C}$ is taken from $A$ to $B$ as shown in the given $PV$ indicator diagram. The work done by the system will be _______ $\times {10}^{-1} \mathrm{J}.$ [Given, $R=8.3 \mathrm{J} {\mathrm{mole}}^{-1} \mathrm{K}, \ln 2=0.6931$] (Round off to the nearest integer)
