Q. A gaseous mixture enclosed in a vessel consists of one gm mole of a gas $A$ with $(\gamma=5 / 3)$ and another $B$ with $(\gamma=7 / 5)$ at a temperature $T$. The gases $A$ and $B$ do not react with each other and assumed to be ideal. Find the number of gram moles of the gas if $\gamma$ of the gaseous mixture is $19 / 13$.
