Question

How many moles are in 6.38x10^22 molecules/atoms of CO2?

Answer 1

0.106 moles

Step-by-step explanation:

To solve this problem we will need to use Avogadro's number, it is the number of molecules (or atoms) in one mol.

We convert molecules into moles using that number:

6.38x10²² molecules ÷ 6.023x10²³ molecules/mol = 0.106 moles

There are 0.106 moles in 6.38x10²² molecules of CO₂.
