1.	The vapour pressure of chloroform `(CHCl)_(3)` and dichlorocethene `(CH_(2)Cl_(2))` at `298 K` is `200 mm Hg ` and `415 mm Hg`, respectively. Calculate a. The vapour pressure of the solution prepared by mixing `25.5 g` of `CHCl_(3)` and `40 g` of `CH_(2)_Cl(2)` at `298 K`. b. Mole fractions of each components in vapour phase .A. 90.92 mm HgB. 615.0 mm HgC. 347.9 mm HgD. 285.5 mm Hg
Answer» Correct Answer - A `n_(CHCl_(3))=(25.5)/(119.5)=0.213` `n_(CH_(2)Cl_(2))=(40)/(85)=0.47` `P_(T)=P_(A)^(@)X_(A)+P_(B)^(@)X_(B)` `=200xx(0.213)/(0.683)+41.5xx(0.47)/(0.683)` `=62.37+28.55=90.92`
