The ratio of $\frac{C_p}{C_v}$ for inert gases is

The total pressure of a mixture of non-reacting gases $X$ $(0.6 \ g)$ and $Y$ $(0.45 \ g)$ in a vessel is $740 \ mm$ of $Hg$. The partial pressure of the gas $X$ is $........ \ mm$ of $Hg$. (Nearest Integer) (Given: molar mass $X = 20 \ g \ mol^{-1}$ and $Y = 45 \ g \ mol^{-1}$)

Give the relation between partial pressure and mole fraction.

Internal energy of an ideal gas depends on

At constant volume and temperature conditions,the rate of diffusion $D_A$ and $D_B$ of gases $A$ and $B$ having densities $\rho_A$ and $\rho_B$ are related by the expression:

What is saturated vapor pressure?
