Question

the number of molecules in 3 moles of carbon dioxide are​

Answer 1

Answer:

The reason chemists use moles is it makes it easy to count atoms or molecules by their mass. The actual number 6.022 x 10^23 of objects in a mole is much less important than knowing that a mole of carbon has the same number of atoms as a mole of oxygen and what a mole of each weighs.

Answer 2

Answer:

18.066x1023 molecules of CO2

Explanation:

1mole has 6.023×10^23

3 moles of CO2 contain 3x6.022x1023=18.066x1023 molecules of CO2
