A laboratory student adds 75.0 mL of 8.0 M HCl to enough water to form 500.0 mL of dilute solution. What is the final concentration of the dilute solution?

Answer:

Final concentration of the dilute solution is 1.2M

Explanation:

Dilution formula must be applied in this case to determine the molar concentration of the dilute solution:

M concentrated . Volume concentrated = Volume diluted . M diluted

75 mL . 8 M = 500 mL . M diluted

(75 mL . 8 M) / 500 mL = M diluted

M diluted = 1.2 M
