What is the molarity when 50.0 ml of 2.0 m naoh is diluted to 150 ml?
6.0 m
0.67 m
1.0 m
1.5 m

The molarity of concentrated NaOH solution is 6 M

Explanation:

To calculate the molarity of the concentrated solution, we use the equation:

where,

are the molarity and volume of the concentrated NaOH solution

are the molarity and volume of diluted NaOH solution

We are given:

Putting values in above equation, we get:

Hence, the molarity of concentrated NaOH solution is 6 M
