Question

Which equivalence factor should you use to convert from 4.25 moles of Al to atoms of Al?

Answer 1

Avogadro's number is 1 mol  = 6.02 * 10^23 elements


It means that 1 mol of atoms is 6.02 * 10^23 atoms

1 mol of atoms = 6.02 * 10^23 atoms

From there, if you divide both sides by 1 mol of atoms, you get

1 = 6.02 * 10^23 atoms / 1 mol of atoms.


That means, that to pass from a number of moles of atoms to number of atoms you have to multipby by the conversion factor

          6.02*10^23  atoms Al/ 1 mol Al


That is the second option of the list.
