Benzeneand toluene form ideal solution over the entire range of composition.
Thevapour pressure of pure benzene and naphthalene at 300 Kare 50.71
mm Hg and32.06 mm Hg respectively. Calculate the mole fraction of benzene
in vapourphase if 80 g of benzene is mixed with 100 g of toluene.
Thepartial pressure of ethane over a solution containing 6.56 ×10−3g of ethane is 1 bar. If the solution contains 5.00 × 10−2g of ethane, then what shall be the partial pressure of the gas?
Asample of drinking water was found to be severely contaminated withchloroform (CHCl3)supposed to be a carcinogen. The level of contamination was 15 ppm(by mass):
(i) express this in percent by mass
(ii) determine the molality ofchloroform in the water sample.
