Answer :
Final answer:
Approximately 23.31 mL of the stock solution would need to be diluted in order to obtain a 1.55 M solution of hydrochloric acid.
Explanation:
To find the volume of stock solution that needs to be diluted, we can use the formula for dilution of a solution: C1V1 = C2V2.
Let's assign the following values:
- C1 = 12.4 M (concentration of the stock solution)
- V1 = unknown (volume of the stock solution to be diluted)
- C2 = 1.55 M (desired final concentration)
- V2 = 185 mL (desired final volume)
Substituting these values into the formula, we get:
12.4 M * V1 = 1.55 M * 185 mL
To solve for V1, we can rearrange the equation:
V1 = (1.55 M * 185 mL) / 12.4 M
Calculating this expression, we find:
V1 ≈ 23.31 mL
Therefore, approximately 23.31 mL of the stock solution would need to be diluted in order to obtain a 1.55 M solution of hydrochloric acid.
