Enough water is added to 50.0 mL of a 0.660 M NaOH solution in order to bring the total volume to 450.0 mL. What is the molarity of this diluted solution?

The final molarity of this diluted solution is equal to 0.073 M.

Given the following data:

To determine the final molarity of this diluted solution:

Mathematically, the relationship between the molarity of a solution and volume is given by the formula:

Where:

Making the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Final molarity = 0.073 M

0.073 M

Explanation:

M1*V1 = M2*V2

M1 = 0.660 M

V1 = 50.0 mL

V2 = 450.0 mL

0.660M * 50.0 mL = M2*450.0 mL

M2 = 0.660M*50.0/450.0 = 0.073 M
