      -1766 kJ. i. -163 kJ/mol. ii. increases. The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first solution, the molarity will clearly be equal to 1.0M because there are 1.0 moles of NaCl and a solution volume of 1.0 L.

      The unit for this is kJ/mol. Sometimes you see older references that use kcal/mol. The conversion between calories and Joules is 4.184 J = 1.000 cal. Sometimes you also see this number expressed "per gram" rather than "per mole." For example, water's molar heat of vaporization is 40.7 kJ/mol. Expressed per gram, it is 2261 J/g or 2.26 kJ/g.
