- A. 7.7 M
Why not A: “7.7 M” is not 8.0 M.
- B. 2.0 M
Why not B: “2.0 M” is not 8.0 M.
- C. 8.5 M
Why not C: “8.5 M” is not 8.0 M.
- D. 8.0 M ✓
Correct answer
D. 8.0 M
Explanation
8.0 M is the value that answers “What is the molarity of a solution containing 4 moles of solute dissolved in 0.5 liters of solution” (option D). Option A (7.7 M) is a different value from 8.0 M. Option B (2.0 M) is a different value from 8.0 M. Option C (8.5 M) is a different value from 8.0 M. Keep 8.0 M as the MCAT fact for this stem.
