$\color{purple}{❍Given}$

Water is evaporated from 135mL of 0.188MK2SO4 solution until the solution becomes 105mL. Thus, molarity of the resultant solution is

$\color{salmon}{❍Solution}$

-0.03024 mol. Now, the volume of lone solution - 105 ml = 0.1052 .. the Molari

= 0.03024

- 0.288 M 0.105

Molarity:

1 so, the correct ans is 0.288M
