Option A

To determine the number of moles in a given number of molecules, we need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole.

Given that we have 8.30 x 10^23 molecules of CO₂, we can divide this value by Avogadro's number to find the number of moles:

8.30 x 10^23 molecules / (6.022 x 10^23 molecules/mole) ≈ 1.376 moles

Therefore, the answer is approximately 1.37 moles. So, option a. 1.37 is the correct choice.
