Answer :
Final answer:
There are approximately [tex]1.0798 x 10^25[/tex] Oxygen atoms in 35.9 moles of As2O5 because one molecule of As2O5 contains 5 Oxygen atoms.
Explanation:
To calculate the number of Oxygen atoms in 35.9 moles of As2O5, you first need to understand that one molecule of As2O5 contains 5 Oxygen atoms. In terms of moles, one mole of As2O5 contains 5 moles of Oxygen. Thus, if we have 35.9 moles of As2O5, we will have 5 * 35.9 = 179.5 moles of Oxygen. Keep in mind that a mole is a counting unit for chemistry and the Avogadro's number tells us that there are about 6.022 x 10^23 entities in one mole. In conclusion, the number of Oxygen atoms in 35.9 moles of As2O5 would be 179.5 moles of Oxygen *[tex]6.022 x 10^23[/tex]atoms/mole, that means approximately [tex]1.0798 x 10^25[/tex]Oxygen atoms.
