Question

Degree of dissociation of three binary electrolytes AB,CD and EF are 60%, 20% and 100% in the solution having same mole fraction of water ratio of lowering in vapour pressure of their solution is

Answer 1

calculate the mass of 1 dm3 of NH3 gas at 30°c 1000mmhg pressure considering tha NH3 behave ideally?

V1 = 302 ml

P1 = 0.52 atm

P2 = ?

V2 = 69 ml Boyle's Law P1V1 = P2V2

P2 = P1V1/V2 P2 =

(0.52 atm)(302 ml)/69 ml

P2 = 2.3 atm...
