Answer :
Answer
6.1621 x 10²³ atoms of zinc
Procedure
To convert from grams to moles, use the molecular weight of zinc which is 65.38 g/mol.
To convert from moles to atoms, use the Avogadro's number: 6.0221408 x 10^23 atoms/ mol.
[tex]66.9\text{ g Zn}\frac{1\text{ mol}}{65.38\text{ g}}\frac{6.0221408\text{ }\times10^{23}\text{ atoms}}{1\text{ mol}}=6.1621\text{ }\times10^{23}[/tex]
