Answer:
[tex]atoms=1.2x10^{24}atomsSi[/tex]
Explanation:
Hello there!
In this case, by considering the mass-mole-particles relationships, it is possible to compute the atoms of silicon by firstly computing the moles via its atomic mass (28.1 g/mol):
[tex]mol=56gSi*\frac{1molSi}{28.1gSi} =2.0molSi[/tex]
Next, via the Avogadro's number, we can compute the atoms of silicon:
[tex]atoms=2.0gSi*\frac{6.022x10^{23}atomsSi}{1molSi}\\\\atoms=1.2x10^{24}atomsSi[/tex]
Best regards!
