Answer:

[tex]n_{Si}=2.41molSi[/tex]

Explanation:

Hello,

In this case, one must use the atom-mole relationship given by the Avogadro's number as shown below, in order to compute the required moles:

[tex]n_{Si}=1.45x10^{24}atomsSi*\frac{1molSi}{6.022x10^{23}atomsSi} \\n_{Si}=2.41molSi[/tex]

Best regards.
