Answer:

Data:

KH = 1.4 x 10-3 mol L-1


P =0.5 atm

Solution:

 

KH = C/P

 

1.4 x 10-3 = C/0.5

C =1.4 x 10-3x 0.5

No. of moles in oxygen in 100 ml= 1.4 x 10-3x 0.5 x 100/1000=1.4 x10-4 x 0.5

Wt. of oxygen in 100 ml = 1.4 x10-4 x 0.5 x32 = 2.24x 10-3g= 2.24mg

Hence the correct option is (d) 2.24 mg
