Question

Convert 5.65 x 10^26 atoms of phosphorus to moles

Answer 1

938.54 moles

Step-by-step explanation:

To find the number of moles in a substance given it's number of entities 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 = \frac{5.65 * {10}^(26) }{6.02 * {10}^(23) } \\ = 938.5382`

We have the final answer as

938.54 moles
