138929 A metal jar has a gas of volume $10^{-3} \mathrm{~m}^{3}$ at a pressure of $2 \times 10^{5} \mathrm{~Pa}$ and temperature $400 \mathrm{~K}$. The jar has small hole and hence the gas leaks into atmosphere. The pressure and temperature of atmosphere is $10^{5} \mathrm{~Pa}$ and $300 \mathrm{~K}$ respectively. If $R$ is the gas constant, the number of moles of the gas that has leaked into atmosphere is
