414. At 25 °C, the saturated vapor pressure of carbon tetrachloride CCl4 is 19.06 kPa, and that of chloroform CHCl3 is 26.53 kPa. Liquid mixtures of these substances have properties close to ideal. Calculate the total vapor pressure of CCl4 and CHCl3 and the mole fraction of CCl4 in the gas phase over a solution containing 1 mol of CCl4 and 3 mol of CHCl3.
