Answer:
3.43 * 10^23 atoms of zinc
Explanation:
According to Avogadro's law, one mole of a substance contains a certain number of atoms of the substance commonly referred to as the Avogadro's number.
We already know from Avogadro's law that;
1 mole of zinc contains 6.02 * 10^23 atoms of zinc
Therefore;
0.57 mole of zinc will contain 0.57 * 6.02 * 10^23/1
which gives us 3.43 * 10^23 atoms of zinc
