Question 1 (16 marks): Solution A contains water and ethanol, and Solution B has non-volatile compound X and ethanol as shown in Figure 1. At 25C, the vapour pressure of pure ethanol is 7.9kPa. a) Determine the density of solution A at 25C. b) Determine the molar mass of the non-volatile compound in Solution B if the added compound X has reduced the vapour pressure of ethanol to 7.5kPa.
