The bacteria have an initial concentration of 1000 cells/cm3 . Each cell divides once every 30 minutes. Calculate how long it wi
Levart [38]

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

  • <u>After 60 minutes </u>

concentration = 4000 cells / cm³

  • <u>After 90 minutes </u>

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 )
