Chemistry
1 answer:
Leno4ka [110]3 years ago
5 0

Answer:

The answer is

<h3>1.74 × 10²⁴ potassium atoms</h3>

Explanation:

To find the number of atoms given the number of moles we use the formula

<h3>N = n × L</h3>

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 = 2.89 moles

We have

N = 6.02 × 10²³ × 2.89

We have the final answer as

<h3>1.74 × 10²⁴ potassium atoms</h3>

Hope this helps you
