At 1000C, the vapour pressure of a solution of 6.5 g. of a solute in 100g. water is 732 mm. What is the boiling point of the solution? (Kb = 0.52)

Question

Vikas TU · Answer

Raoult's aw of Partial pressure
Pa^0 - Ps / Ps = nb /na
Putting the values
28 / 732 = 6.5 * 18 / Mb *100
Mb = 30.6
Del Tb = 0.52 * 6.5 * 1000/ 30.6 * 100
=> 1.10
Boiling point = 100+ 1.10
=> apx 101 degree centigrade
