MCQ - 6-2192

Question:

Two solutions of a substance (non-electrolyte) are mixed in the following manner. 480 mL of 1.5 M first solution + 520 mL of 1.2 M second solution. What is the molarity of the final mixture?

  1. 1.20 M
  2. 1.344 M
  3. 1.50 M
  4. 1.344 M

Correct Answer: B

Explanation:

Molarity of a mixture, Mmix can be calculated by: Mmix = (M1V1 + M2V2) / (V1 + V2) = (1.5 x 480) + (1.2 x 520)/(480 + 520) = 720+624/1000 = 1.344 M
