A 64.0 mL sample of 1.0 M NaOH is mixed with 47.0 mL of 1.0 M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. The temperature of each solution before mixing is 22.6 °C. After adding the NaOH solution to the coffee cup, the mixed solutions are stirred until reaction is complete. Assume that the density of the mixed solutions is 1.0 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g •°C), and that no heat is lost to the surroundings. The ΔΗrxn for the neutralization of NaOH with H2SO4 is –114 kJ/mol H2SO4. What is the maximum measured temperature in the Styrofoam cup?

When 20.0 mL of 1.0 M H3PO4 is added to 60.0 mL of 1.0 M NaOH at 25.0 degrees celcius in a calorimeter, the temperature of the aqueous solution increases to 35.0 degrees celcius. Assuming that the specific heat of the solution is 4.18 J/(g⋅∘C), that its density is 1.00 g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate ΔH in kilojoules/mol H3PO4 for the reaction.
