3M
3M is the molarity of a koh solution if 200 ml of the solution contains 0. 6 moles KOH.
Molarity : Molarity is defined as the number of moles of solute present in one liter of solution.
We know that,
Molarity = [tex]\frac{n*1000}{v}[/tex]
where,
n = moles of solute of KOH = 0.6
V= volume of solution in ml= 200 ml
Now on substituting the values in the molarity formula,
molarity = [tex]\frac{0.6*1000}{200}[/tex] = 3M/L
Therefore, molarity = 3M
