Question 1

A KCl solution is prepared by dissolving 25.0 g KCl in 250.0 g of water at 25 °C. What is the vapour pressure of the solution if the vapour pressure of water at 25 °C is 23.76 mmHg?
◦ 24.9 mmHg
◦ 23.2 mmHg
◦ 21.6 mmHg
◦ 22.7 mmHg

Question 2

At a given temperature the vapour pressures of benzene and toluene are 183 mmHg and 59.2 mmHg, respectively. Calculate the total vapour pressure over a solution of benzene and toluene with Xbenzene = 0.580.
◦ 242 mmHg
◦ 121 mmHg
◦ 131 mmHg
◦ 106 mmHg
