Help (Mass Transport and Rate Phenomena)

7. 1.8L of 20% acetone (molar basis) and 80% water is placed in a 2.0L bottle at 25C. The bottle originally has dry air occupying the remaining 0.2L at atmospheric pressure. The bottle is capped and stored in an incubator at 45C for many days. Assume that Raoult's Law applies and that no change in the liquid volume occurs as the temperature increases from 25C to 45C a. What will be the pressure of the enclosed mixture after the temperature increase? Hint: you may need to use the combined gas law T1P1=T2P2 b. What will the composition (mole fraction of each component) of the gaseous mixture
