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 \(Y =45\,g\,mol ^{-1}\) )
- A \(550\)
- B \(552\)
- C \(553\)
- D \(555\)
Answer & Solution
Correct Answer
(D) \(555\)
Step-by-step Solution
Detailed explanation
\(P _{ X }=\chi_{ X } P _{ T }\) \(=\frac{\frac{0.6}{20}}{\frac{0.6}{20}+\frac{0.45}{45}} \times 740\) \(P _{ X }=555\,mm\,Hg\)
