Difficulty: Medium
About this MCQ
Medium MCAT item. Correct choice: C. 0.8 M.
- A. 1.3 M
Why not A: “1.3 M” is not 0.8 M.
- B. 20 M
Why not B: “20 M” is not 0.8 M.
- C. 0.8 M ✓
- D. 0.5 M
Why not D: “0.5 M” is not 0.8 M.
Correct answer
C. 0.8 M
Explanation
0.8 M is the value that answers “What is the molarity of a solution containing 4 moles of solute dissolved in 5 liters of solution” (option C). Option A (1.3 M) is a different value from 0.8 M. Option B (20 M) is a different value from 0.8 M. Option D (0.5 M) is a different value from 0.8 M. Keep 0.8 M as the MCAT fact for this stem.
