Bacterium divides every 35 minutes. If a culture containing 10 5 cells per mL is grown for 175 minutes, what will be the cell concentration per mL after 175 minutes?
Options
- A5 × 1 0 5 cells
- B3 5 × 1 0 5 cells
- C3 2 × 1 0 5 cells
- D1 7 5 × 1 0 5 cells
Correct answer
C. 3 2 × 1 0 5 cells
Step-by-step solution
1 × 1 0 5 ⟶ 35 min 2 × 1 0 5 ⟶ 70 min 4 × 1 0 5 ⟶ 105 min 8 × 1 0 5 ⟶ 140 min 1 6 × 1 0 5 ⟶ 175 min 3 2 × 1 0 5
