Aculture of e. coli bacteria doubles every 40 minutes. if there are 50 bacteria initially, how many will there be after 12 hours? round your answer to the nearest whole number

There will be 13107200 number of bacteria after 12 hours

Explanation:

1 hour = 60 minutes

So, 12 hours = () minutes = 720 minutes

Initially there are 50 bacteria.

As number of bacteria doubles in every 40 minutes therefore rate of increase in number of bacteria will be similar to a first order reaction.

Hence, number of bacteria after 720 minutes = = 13107200
