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