You have an naoh solution that has a concentration of 0.660 m and a volume of 50.0 milliliters. you dilute this solution with water to a total volume of 450.0 milliliters. what is the final concentration of the solution?

0.073 M

We are given;

Initial concentration, M1 of NaOH solution as 0.660 M

Initial volume,V1 of solution as 50.0 mL

Final volume,V2 of solution after dilution as 450 mL

We are required to calculate the final concentration, M2.

We are going to use the concept on dilution.

Using dilution formula,

M1V1 = M2V2

M2 = M1V1 ÷ V2

     = (0.660 M × 50.0 mL) ÷ 450.0 mL

     = 0.0733 M

     = 0.073 M

Thus, the final concentration of the solution is 0.073 M
