Answer:

$\huge{ \boxed{3.49 * {10}^(24) }}$

Step-by-step explanation:

To find the number of atoms of He we use the formula

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 = 5.80 moles

$\therefore \: N = 5.8 * 6.02 * {10}^(23) \\ = 3.49 * {10}^(24)$
