you were given 1.2*10^7 cells/mL solution. how many cells would be present in 100 microliters
To determine the number of cells present in 100 microliters (µL), we need to convert the given concentration from cells/mL to cells/µL and then multiply it by the volume.
Given:
Concentration = 1.2 x 10^7 cells/mL
Volume = 100 µL
To convert the concentration from cells/mL to cells/µL, we need to divide it by 1000 (since there are 1000 µL in 1 mL):
Concentration (cells/µL) = (1.2 x 10^7 cells/mL) / 1000 = 1.2 x 10^4 cells/µL
Now, we can calculate the number of cells in 100 µL:
Number of cells = Concentration (cells/µL) x Volume (µL)
= 1.2 x 10^4 cells/µL x 100 µL
= 1.2 x 10^6 cells
Therefore, there would be 1.2 x 10^6 cells present in 100 microliters of the solution.
