Answer:

1.198×[tex]10^{24}[/tex] atoms

Explanation:

To answer this, you will need to use Avogadro's number (6.02×10^23) to convert between moles and atoms.

You can use dimensional analysis to set up and solve the equation as seen below:

[tex]\frac{1.990 mol Zinc}{1}[/tex] × [tex]\frac{6.02*10^{23} atoms }{1 mol Zinc}[/tex]  = 1.198×[tex]10^{24}[/tex] atoms

Hope this helps!
