Calculating Enthalpy in a Calorimeter Experiment

When 25.0 mL of 1.0 M H2SO4 is added to 50.0mL of 1.0M of NaOH at 25.0 degrees C in a calorimeter, the temperature of the aqueous solution increases to 33.9 degrees C. Assuming that the specific heat of the solution is 4.18J/(g*degree C), that its density is 1.00g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate enthalpy in kilojoules for that reaction.
H2SO4 (aq) + 2NaOH (aq)---> 2H20(l)+ Na2SO4 (aq)

why ∆T is not 33.9 -25 ?


J.R. S.

Correct. I misread it and thought the increase in temp was 33.9 degrees. My bad.
