How can atoms make up all of the substances around you?
answer: it contains 0.298 mole of na and 0.298 mole of cl.
explanation:to get the number of moles of each element in nacl we should know that every mole of nacl contains 1.0 mole of na and 1.0 mole of cl:
nacl → na + clit is clear that each mole of nacl contains one mole of na and one mole of cl.using cross multiplication:
1.0 mol nacl → 1.0 mol na
0.298 mol nacl → mol nathe number of moles of na atoms in nacl = (1.0 mol na x 0.298 mol nacl) / (1.0 mol nacl) = 0.298 mol of na atoms.by the same way; the number of moles of cl atoms = (1.0 mol cl x 0.298 mol nacl) / (1.0 mol nacl) = 0.298 mol of cl atoms.
