Answer:
To convert the number of molecules of carbon dioxide (CO2) to the number of moles, we can use Avogadro's number, which relates the number of particles to the number of moles:
1 mole of any substance contains 6.022 x 10^23 particles (Avogadro's number)
Therefore, to find the number of moles of CO2 in 4.57 x 10^24 molecules, we can divide the number of molecules by Avogadro's number:
Number of moles = Number of molecules / Avogadro's number
Number of moles = 4.57 x 10^24 / 6.022 x 10^23
Number of moles = 7.594 moles (rounded to three significant figures)
Therefore, there are approximately 7.594 moles of carbon dioxide (CO2) in 4.57 x 10^24 molecules.
