WebMoles are not mass. Moles are counts of particles. Thus, when one particle breaks into two particles you double the number of particles. Likewise, when you have 1 mole of NaCl and the particles break apart, you now have 2 moles in total -- 1 mole of Na⁺ ions and 1 mole of Cl ⁻ ions. ( 24 votes) Show more...
