Answer:

1.204 × 10²¹ units

Step-by-step explanation:

The number of formula units 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 = 0.002 × 6.02 × 10²³

We have the final answer as

1.204 × 10²¹ units

Hope this helps you
