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
