Answer: 3M

Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute $KOH$ = 0.6 moles

$V_s$ = volume of solution in ml= 200 ml

Now put all the given values in the formula of molarity, we get

$Molarity=\frac{0.6moles\times 1000}{200ml}=3mole/L$

Therefore, the molarity of solution will be 3M.
