Answer:

1.93 × 10²⁴ atoms

Explanation:

The number of atoms in a substance can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 3.21 × 6.02 × 10²³

We have the final answer as

1.93 × 10²⁴ atoms
