Calcium lactate is a salt of weak organic acid and strong base represented as `Ca(LaC)_(2).` A saturated solution of `Ca(LaC)_(2)` contains 0.6 mole in 2 litre solution. pOH of solution is 5.60. If `90%` dissociation of the salt takes place then what is `pK_(a)` of lactic acid?

`2.8-log(0.54)`

`2.8+log(0.54)`

`2.8+log(0.27)`

None of these
