<h3>
Answer:</h3>
0.073 M
<h3>
Explanation:</h3>
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.
- Dilution involves addition of solvent to a concentrated solution to make it dilute.
- This results to an increase in the final volume of solution and a decrease in the concentration of the solution.
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

Neutrons and protons are tiny particles that are within the nucleus. Neutrons and protons make up the nucleus of the cell and the ratio of neutrons determine the stability of the atomic nuclei. The nucleus will become unstable if the ratio of neutrons to protons are not within the appropriate amount.</span>
