A mole of table sugar (sucrose, C12H220,1) is 342.3 g. A mole of table salt (sodium chloride, NaCl) is 58.45 g. What does the difference in macroscopic size of a mole of sugar and a mole of salt suggest about their microscopic representative particles? Considering the size of a mole of these materials, why do you think chemists use the concept of moles when dealing with macroscopic quantities?
