In order to judge the effect of solvent on the interaction b

In order to judge the effect of solvent on the interaction between ions in solution, calculate the potential energy in kJ/mol of interaction between a sodium ion and a chloride ion, each treated as a point charge of + or -e, separated by 9 Angstroms in water. The dielectric constant of water at room temperature is 78.3. Hint: your answer will come out negative because the interaction is attractive. Also, you\'ll need to multiply your number by Avogadro\'s number to get it on a per mole basis.
