Question

Calculate the number of atoms in 5.42 mol of Sodium.

Answer 1

`\huge{ \boxed{3.26 * {10}^(24) \: atoms}}`

Step-by-step explanation:

To find the number of atoms of sodium we use 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 = 5.42 mol

`\therefore \: N = 5.42 * 6.02 * {10}^(23) \\ = 3.26 * {10}^(24)`
