Answer :
Final answer:
To prepare a 250. ml solution with a concentration of 0.750 M from a 6.00 M HCl solution, you would need to use 31.3 ml of the HCl solution.
Explanation:
This is a dilution problem and can be solved using the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume. Since we are looking for the initial volume (V1), we will rearrange the formula to V1 = M2 * V2 / M1.
Substituting the given values, we get V1 = (0.750 M * 250 ml) / 6.00 M = 31.25 ml. Therefore, 31.3 ml of a 6.00 M HCl solution is required to prepare a 250 ml solution with a concentration of 0.750 M (D).
