Answer:

$\huge{ \boxed{0.249 \: \text{moles}}}$

Step-by-step explanation:

The number of moles of zinc atoms 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 N = 1.5 × 10²³ zinc atoms.

$\therefore \: n = \frac{1.5 * {10}^(23) }{6.02 * {10}^(23) } \\ = 0.249 \: \text{moles}$
