Chemistry

You mix 50.0 mL of a weak monoprotic acid with 50.0 mL of NaOHsolution in a coffee cup calorimeter. Both solutions (and thecalorimeter) were initially at 22.0C. The finaltemperature of the neutralization reaction was determined to be22.5C.

a) What is the total amount of heat evolved in this reaction?Show all work.

b) If 0.135 moles of the monoprotic acid were neutralized inthis reaction, what is the molar heat of neutralization (enthalpy)for this reaction?
