Question

Bacterium divides every 35 min. If a cultur contaning 105 cell/ ml and it grown for 175 min what will be cell concentration per ml after 175 min

Answer 1

Let's consider that there's a single bacterium in

he culture. 175 minutes equals five 35 minutes,

thus the bacterium divides 5 times. After 5

divisions number of bacteria would be 32 = 2"5

Now, for the solution of this question simply

multiply the initial number of bacteria with 2

raised to the power the number of divisions.

e: 100,000 x 25 = 32,00,000

[ hope this helps! :)
