Final answer:

Approximately 9.26 × 1021 atoms of zinc are in 1.00 g.

Step-by-step explanation:

The molar mass of zinc is 65.4 g/mol. Since the student is asking for the number of atoms of zinc in 1.00 g, we can use the molar mass to convert from grams to moles.

To do this, we divide the given mass (1.00 g) by the molar mass of zinc (65.4 g/mol).

By dividing 1.00 g by 65.4 g/mol, we get approximately 0.0153 mol. Since 1 mol of any substance contains 6.022 × 1023 atoms of that substance, we can use this information to calculate the number of atoms of zinc in 1.00 g.

Therefore, there are approximately 0.0153 mol × 6.022 × 10^23 atoms/mol = 9.26 × 1021 atoms of zinc in 1.00 g.
