What is the Molarity of a solution prepared by dissolving 74.5 g of NaOH in water to make 1.50 L of solution? A. 1.24M
B. 40.0M
C. 49.6M
D. 1.86M

74.5 g of NaOH is dissolved in water to 1.50L of Solution .

We have been asked to find the molarity of solution

Formula to calculate Molarity

First Let's find the Molar Mass of NaOH

Put the given value we get

Now calculating the molarity of given solution

So, the molarity of the solution is 1.24M

Option (A) is your correct answer.
