Answer:

3 moles

Step-by-step explanation:

200 ml is 1/5 of a liter, so the answer is five times the number of moles present in the solution. 0.6 moles/0.2 liter = x moles/1.0 liter. Solving for x gives 0.2 x = 0.6 or x = 3.0 M.

Answer: 3M

Step-by-step explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :


Molarity=(n* 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=(0.6moles* 1000)/(200ml)=3mole/L

Therefore, the molarity of solution will be 3M.
