Answer:
2.38 x 10²⁵ molecules
Step-by-step explanation:
To calculate the number of molecules in 39.6 moles of CO₂, we can use Avogadro's number, which is approximately 6.02 x 10²³ molecules per mole.
Therefore, the number of molecules in 39.6 moles of CO₂ would be:
39.6 moles x (6.02 x 10²³ molecules/mole) = 2.38 x 10²⁵ molecules of CO₂.
So, there are approximately 2.38 x 10²⁵ molecules of CO₂ in 39.6 moles of the compound.
