The enthalpy of neutralizatino for the reaction of a strong acid with a strong base is -56 kJ/mol of water produced. How much energy will be released when 230.0 mL of 0.400 M HCl is mixedwith 150.5 mL of 0.500 M NaOH?

How much water is produced in the reaction?

How do I figure out how much water is produced in the reaction? Would I change the HCl and the NaOH to moles?

Yes. The one with the least moles will determine how much water is made.
