Answer:
[tex]6.32 * 10^{15}[/tex]
Explanation:
The molar concentration is defined as the number of moles of a substance in one unit volume of a solution
Here [tex]= 0.0019 * 3.324 * 10^{18}\\= 6.32 * 10^{15}[/tex]
Molar concentration [tex]= 0.0019[/tex] M
The dimensions of bacterial cell are as follows
Diameter [tex]= 1.1[/tex] μm
and length of the bacterial cell [tex]= 3.5[/tex] μm
The volume of the solution is equal to product of area and the length
Thus, volume [tex]= \pi * r^2 * h\\[/tex]
Substituting the given values in above equation, we get -
[tex]= 3.14 * (\frac{1.1}{2} )^2 * 3.5\\[/tex]
[tex]= 3.324[/tex] μm^3
Number of molecules
[tex]= 0.0019 * 3.324 * 10^{18}\\= 6.32 * 10^{15}[/tex]
