Question

200 mL of 3 M HCl is mixed with 300 mL of 2 M HCl. The final molarity is:
  1. A
    2.4 M
    Correct
  2. B
    2.5 M
  3. C
    5 M
  4. D
    2.6 M

Correct answer

2.4 M

Explanation

Total moles = 0.2×3 + 0.3×2 = 0.6+0.6 = 1.2 mol. Total volume = 500 mL = 0.5 L. M = 1.2/0.5 = 2.4 M.
