A large chamber contains dry $N_2$ at $27C$ and $101\mathrm{.}3$kPa. Water is injected into the chamber. After

saturation of the $N_2$ with water vapor, the temperature in the chamber is $27C.$

a$.$ What is the pressure inside the chamber after saturation?

b$.$ How many moles of $H_{2}O$ per mole of $N_2$ are present in the saturated mixture?
