How many chloride ions are in a sample of salt that contains 2 moles of KCl?

Answer 1

1 mole KCl = 1 mol K and 1 mol Cl
2 mol KCl = 2 mol K and 2 mol Cl
2 mol Cl X (6.02 X 10^23) = ions Cl = 1.204 X 10^24 ions Cl

Answer 2

1mole of any element is 6.02*10^23 particles

there is one mole of Cl in KCl, so you will have 6.02*10^23

now you have 2 mole of KCl, so you will have 2*6.02*10^23 = 1.204*10^24 particles

thus you have 1.204*10^24 particles of chloride ions
