Answer:
43.5 mL
Explanation:
We are given;
- Molarity of dilute acetic acid is 1.74 M
- Volume of the solution that needs to be prepared is 200 mL
- Molarity of the stock solution 8 M
We are required to determine the volume of acid that must be used.
- We need to know the dilution formula;
- According to the dilution equation;
M1V1 = M2V2
Rearranging the formula;
V1 = M2V2 ÷ M1
= (1.74 M × 200 mL) ÷ 8 M
= 43.5 mL
Therefore, the volume of the concentrated acid that must be added is 43.5 mL
