... In using the term mole for ionic substances, we mean the number of formula units of the substance. For example, a mole of sodium carbonate, Na2CO3 is a quantity containing 6.023 x 1023 Na2CO3 units. But each formula unit of Na2CO3 contains 2 x 6.023 x 1023 Na+ ions and one CO32ions and 1 x 6.023 x 1 ...
