Explanation: If I asked how many atoms there were in a dozen formula units of BaCl2 , I think you would quickly answer 3 dozen: 12 barium atoms, and 24 chlorine atoms. The question specified molar quantities, and the mole is just another number, admittedly a very large number, i.e. NA = 6.022×1023 mol−1 .

In order to work this out, multiply Avogadro's number - the one I stated at the start of this explanation - by 2 . This will give you the number of molecules in 2 moles of a substance. In other words, 1 mole of atoms is 6.02×1023 atoms. 1 mole of molecules is 6.02×1023 molecules.
