Answer:
The number of atoms are [tex]1.86\times10^{8}[/tex].
Explanation:
Given that,
Diameter [tex]D = 1.40\times10^{2}\ pm[/tex]
[tex]D=1.40\times10^{2}\times10^{-12}\ m[/tex]
Distance = 2.60 cm
We calculate the number of atoms
Using formula of numbers of atoms
[tex]Number\ of\ atoms =\dfrac{2.60\times10^{-2}}{1.40\times10^{2}\times10^{-12}}[/tex]
[tex]Number\of\atoms =1.86\times10^{8}[/tex]
Hence, The number of atoms are [tex]1.86\times10^{8}[/tex].
