Question
![A 104.2 mL sample of 1.00 M NaOH is mixed with 52.1 ml of 1.00 MH2SO, 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 23.05°C. After adding the NaOH solution to the coffee cup and stirring the mixed solutions with the
thermometer, the maximum temperature measured is 30.90 °C. Assume that the density of the mixed solutions is
1.00 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.
