Chapter 17, Problem 5P

Sodium chloride (table salt) consists of sodium ions of charge + e arranged in a crystal lattice with an equal number of chlorine ions of charge –e. the mass of each sodium ion is 3.82 x 10^-26 kg and that of each chlorine ion 5.89 x 10^-26 kg. Suppose that the sodium ions could be separated into one pile and the chlorine ions into another. What mass of salt would be needed to get 1.00 C of charge into the sodium ion pile and -1.00 C into the chlorine ion pile?
