If you have 8.45 x 10^27 molecules of H2O, how many moles of water do you have?

Explanation:

To find the number of moles in a substance given it's number of entities 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 = 8.45 x 10^27 molecules of H2O

We have

We have the final answer as
