Solutions Question 12

Question 12 - 31 January - Shift 1

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 $X=20$ and $Y=45 g mol^{-1}$ )

Show Answer

Answer: (555)

Solution:

$P_X=\chi_X P_T$

$=\frac{\frac{0.6}{20}}{\frac{0.6}{20}+\frac{0.45}{45}} \times 740$

$P_X=555 mm Hg$
