Answer:
7 hours
Explanation:
Given, generation time of the species is 1 hour which means that after every 1 hour the cells double in number.
At 0 time = 100 cells/ml
After 1 hours = 200 cells/ml
After 2 hours = 400 cells/ml
After 3 hours = 800 cells/ml
After 4 hours = 1600 cells/ml
After 5 hours = 3200 cells/ml
After 6 hours = 6400 cells/ml
After 7 hours = 12800 cells/ml
Thus, after 7 hours the culture will contain approximately 10000 cells/ml.
