Question

How many moles are there in 3.612 x 1024 formula units of Na2SO4?

Answer 1

Answer:

Theanswer is 6 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L}$

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

$n = \frac{3.612 \times {10}^{24} }{6.02 \times {10}^{23} }$

We have the final answer as

6 moles
