I was confused with part c of question E.17 in the Atkins 7E textbook. Which sample in each of the following pairs contains the greater number of moles of atoms. (C) 7.36 x 10^27 atoms of Ru or 7.36 x 10^27 atoms of Fe. I began with trying to convert the atoms back to moles by dividing the 7.36 x 10^27 atoms by 6.022 x 10^23 and got 1.22 x 10^4 moles for both Ru and Fe so I suspected both have the same # of moles of atoms but it doesn't seem like they can be both equal since they're different elements but does anyone else know what to do?
You did not need to do any calculations for this problem because it already states that there are equal amounts of atoms. Therefore, none from the pair contains more moles of atoms. They contain equal amounts.
