(a) A solution contains 5.85\; g\; NaCl (Molar mass 58.5\; g\; mol^{-1}) per litre of solution. It has an osmotic pressure of 4.75\; atm at 27^{\circ}C. Calculate the degree of dissociation of NaCl in this solution. 
(Given :R=0.082\; L\; atm\; K^{-1}\; mol^{-1})

Answers (1)

a) π = i CRT

4.75 = i x 5.85/58.5 x 0.082 x 300

i = 1.93

b) Partial pressure of gas in liquid is directly proportional to its solubility or mole fraction. Air is diluted with helium in the tanks used by scuba divers to prevent bends
