Sodium chloride 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 × 10^-26 kg and that of each chlorine ion 5.89 × 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?
