1) At 40 degree C the vapor pressure of the n-pentane (n-c5H12) is 873mm and the vapor pressure of n-heptane (n-C7H16) is 92mm use raoults law to calculate the vapor pressure at 40 degree C of a 3:1 molar mixture of n-pentane and n-heptane do the same for a mixture containing 50 g of each component.

2) A solution consist of 10 g of liquid x whose molecular weight is 50 and 9 g of liquid y whose molecular weight is 30. the vapor pressure of pure x and pure y at 20 degree C are 40 and 70mm. calculate the mole fraction of x and y in the solution. if the solution is ideal, what is the partial pressure of x over the solution at 20 degree C? to what value would you reduce the external pressure on the system in order to initiate boiling at 20 degree C?
