How to Calculate the Number of Moles in a Given Number of Molecules
When we want to find the number of moles in a substance given its number of entities, we can use a specific formula. The formula is:
n = N/L
Where:
n is the number of moles
N is the number of entities
L is Avogadro's constant, which is 6.02 Ã 10^23 entities
Using the data from the question, we can calculate the number of moles in 1.81 x 10^24 molecules of CO2:
n = 1.81 x 10^24 / 6.02 x 10^23 = 3.006644...
Therefore, the final answer is approximately 3.01 moles.
I hope this explanation helps you understand how to calculate the number of moles in a given number of molecules.
