About this MCQ
Medium MCAT item. Correct choice: C. 0.5 M.
- A. 1.0 M
Why not A: “1.0 M” is not 0.5 M.
- B. 12.5 M
Why not B: “12.5 M” is not 0.5 M.
- C. 0.5 M ✓
- D. 0.2 M
Why not D: “0.2 M” is not 0.5 M.
Correct answer
C. 0.5 M
Explanation
0.5 M is the value that answers “What is the molarity of a solution containing 2.5 moles of solute dissolved in 5 liters of solution” (option C). Option A (1.0 M) is a different value from 0.5 M. Option B (12.5 M) is a different value from 0.5 M. Option D (0.2 M) is a different value from 0.5 M. Keep 0.5 M as the MCAT fact for this stem.
