What is the relationship between the volatility of a liquid and its vapour pressure?
Acetone has a vapour pressure of 53.3 kPa at 39.5 °C and 202.6 kPa at 78.6 °C. From the above data, obtain an equation to correlate the vapour pressure of acetone. (The equation should be in the form In(P)= -A/T + Co where P, is in kPa units. Find numerical values for A and Co) A= 5756 K, Co = 17.989 A= 4756 K, Co = 16.989 A= 3756 K, Co = 15.989 A= 2756 K, Co = 14.989

The boiling temperature of a substance increases by 0.63⁰C by dissolving 565 g of an organic solvent, consisting of 5.25 g of C and H, with a Ma of 78 and a density of 0.88 g/cm3, at 298K. Considering that this solvent is Kf = 5.12 K kg/mol and Kb = 2.53 K kg/mol, and its pure vapor pressure is 103 tons at 298K, find the freezing point drop, vapor pressure and osmotic pressure of the solvent in the solution.
