About this MCQ
Medium MCAT item. Correct choice: C. 2.0 M.
- A. 8 M
Why not A: “8 M” is not 2.0 M.
- B. 2.5 M
Why not B: “2.5 M” is not 2.0 M.
- C. 2.0 M ✓
- D. 1.7 M
Why not D: “1.7 M” is not 2.0 M.
Correct answer
C. 2.0 M
Explanation
2.0 M is the value that answers “What is the molarity of a solution containing 4 moles of solute dissolved in 2 liters of solution” (option C). Option A (8 M) is a different value from 2.0 M. Option B (2.5 M) is a different value from 2.0 M. Option D (1.7 M) is a different value from 2.0 M. Keep 2.0 M as the MCAT fact for this stem.
