Question
A 60.0 mL sample of 1.0 M NaOH is mixed with 45.0 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 25.9°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 speciffic heat of the mixed
solutions is 4.18 J/(g •°C), and that no heat is lost to the surroundings. The AHrxn for the neutralization of NaOH with H2SO4 is -114 kJ/mol H2SO4.
