Each cell divides to form two new cells every 30 minutes. If a culture starts out with exactly 100 bacterial cells how many bact
eria will be present after 3 hours?
1 answer:
So, after 30 mins we have:
100*2
After 1 hour: 100*2*2, etc
the number of 2s will be the number of time they will divide: 3 hrs divided by 0.5 hour: this is six times.
So the final number of cells will be:
So after 3 hrs there will be 6400 cells there!
