A) 0.67
B) 0.75
C) 0.33
D) 0.50
Correct Answer: A
Solution :
[a] Total vapour pressure = vapour pressure of pure benzene + vapour pressure of \[=100+50=150\text{ }mm\] We know, \[P_{{{C}_{6}}{{H}_{6}}}^{{}^\circ }=P\times {{X}_{C6H6}}\] \[100=150\times {{X}_{C6H6}}\] \[{{X}_{C6H6}}=\frac{100}{150}=0.67\]You need to login to perform this action.
