<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is 
<u>Explanation:</u>
We are given:
Proteus vulgaris divides and doubles every 28 minutes
Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)
Number of times Proteus vulgaris doubles in 6 hours = 
Calculating the number of bacteria after 6 hours under ideal conditions:
We are given:
Initial population = 500 cells
Number of times it doubles = 12.857 times
Final Proteus vulgaris population = 
Hence, the final population of Proteus vulgaris after 6 hours is
