A solution of 1.699 g of dichloromethane and 9.953 g of dibromomethane at 25°C was experimentally measured to have a solution vapor pressure of 42.3 kPa. The vapor pressures of the pure solvents, dichloromethane and dibromomethane, at 25°C are published by NIST to be 435- and 44.4-mm Hg, respectively.

1) Calculate the vapor pressure of each component and the total pressure of the solution assuming the behavior of this solution is ideal.

2) Based on the comparison of two total pressures, experimental and calculated, does this solution deviate from ideal behavior (i.e., Raoult’s Law), and if so in which way?
