At -47°C the vapor pressure of ethyl bromide is 10 mmHg, while that of ethyl chloride is 40 mmHg. Assume that the mixture is ideal. If there is only a trace of liquid present and the mole fraction of ethyl chloride in the vapor is 0.80, a) What is the total pressure and the mole fraction of ethyl chloride in the liquid? b) If there are 5 mol of liquid and 3 mol of vapor present at the same pressure in a), what is the overall composition of the system?
