Difficulty: Medium
About this MCQ
Medium MCAT item. Correct choice: A. 5.0 M.
- A. 5.0 M ✓
- B. 4.7 M
Why not B: “4.7 M” is not 5.0 M.
- C. 5.5 M
Why not C: “5.5 M” is not 5.0 M.
- D. 1.25 M
Why not D: “1.25 M” is not 5.0 M.
Correct answer
A. 5.0 M
Explanation
5.0 M is the value that answers “What is the molarity of a solution containing 2.5 moles of solute dissolved in 0.5 liters of solution” (option A). Option B (4.7 M) is a different value from 5.0 M. Option C (5.5 M) is a different value from 5.0 M. Option D (1.25 M) is a different value from 5.0 M. Keep 5.0 M as the MCAT fact for this stem.
