Question

How many moles are in 4.67 x 10^26 atoms of Iron?

Answer 1

Answer:

775.75 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

$n = \frac{4.67 \times {10}^{26} }{6.02 \times {10}^{23} } \\ = 775.747508...$

We have the final answer as

775.75 moles
