umka2103 [35]

Answer:

There are  \mathbf{8.90172 \times 10^{-14}} moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells

Explanation:

Given that:

The number of molecules present in one bacterial cell is 7.140 \times 10^3 molecules

and the sample  contains 7.512 \times 10^6 molecules.

Number of moles = number of molecules /Avogadro's number

where;

Avogadro's number = 6.023 × 10²³

Number of moles = \dfrac{7.140 \times 10^3}{6.023 \times 10^{23}}

Number of moles = 1.185 \times 10^{-20} moles

So;  1.185 \times 10^{-20} moles  is present in one bacteria cell

Similarly;  the sample  contains 7.512 \times 10^6 molecules.

Therefore; the number of moles present in the bactoX is = 1.185 \times 10^{-20} \times 7.512 \times 10^6

= \mathbf{8.90172 \times 10^{-14}} moles
