0 At 35 C the vapour pressure of CS is 512 mm Hg and of acetone CH COCH3 is 344 mm Hg A solution of CS and acetone in which the mole fraction of CS2 is 0 25 has a total vapour pressure of 600 mm Hg Which of the following statements about solution of acetone CS is true 1 A mixture of 100 ml of acetone and 100 ml of CS has a total volume of 200 ml 2 When acetone and CS2 are mixed at 35 C heat must be absorbed in order to produce a solution at 35 C 3 When acetone and CS2 are mixed at 35 C heat is released 4 Raoult s law is obeyed by both CS and acetone for the solution in which the mole fraction of CS is 0 25 For an ideal gas number of moles per litre in terms of its pressure P gas constant R and temperature
