A 104.4mL sample of 1.8M HNO3 is mixed with a 800mL sample of 0.5M KOH in a Styrofoam cup. If both solutions were initially at 25.2\deg C, and the enthalpy of the neutralization reaction is -57 kJ/mole of H2O formed, what is the final temperature of the mixture? The volume of the formed H2O can be ignored. Assume that the solution has a density of 1.00 g/mL and a specific heat of 4.184 J/g\deg C, and that the Styrofoam cup has an insignificant heat capacity.
