It will take <u>120 minutes</u> for the concentration to become > 15000 cells/cm³
<u>Given data:</u>
Initial concentration ( density ) = 1000 cells / cm³
Target/final concentration = > 15,000 cells /cm³
<h3 /><h3>Calculating the concentration every 30 minutes </h3><h3 />
<em>note</em><em> : Given that each cell divides every 30 minutes </em>
- <u>After the first 30 minutes </u>
Concentration = 2000 cells / cm³
concentration = 4000 cells / cm³
concentration = 8000 cells / cm³
- <u>After 120 minutes </u>
concentration = 16000 cells / cm³
Therefore after 120 minutes the concentration of the cells will be greater than 15000 cells/cm³ ( i.e. 16000 cells/cm³ )
