Question

If 0.25 liters of solution contains 0.030 moles of KOH what is the molarity of the solution?

Answer 1

The molarity of the solution is 0,12 M.

Step-by-step explanation:

We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case KOH) in 1000ml of solution (1 liter):

0,25 L solution----- 0,030 moles of KOH

1 L solution----x= (1 L solution x 0,030 moles of KOH)/0,25 L solution

x= 0,12 moles of KOH ---> The solution is 0,12 M
