Help with Chemistry question PLEASE!! Solutions are combined in a calorimeter to determine the enthalpy of the neutralization reaction.?
The following solutions are combined in a calorimeter to determine the enthalpy of the neutralization reaction.
100.0 mL sodium hydroxide, NaOH, of unknown concentration an excess of 1.3732 M hydrochloric acid, HCl
The experimental value for q is determined to be -2.676 kJ
Knowing that the theoretical value of q for any neutralization reaction is -55.90 kJ/mol H2O, determine the concentration of the sodium hydroxide solution.

moles of water formed = 2.676 kJ / 55.9 kJ/mole
Since the acid is in excess and you are dealing with HCl and NaOH, this is moles of base.
Molarity of base = moles of base / volume of base in L
