A101.2 ml sample of 1.00 m naoh is mixed with 50.6 ml of 1.00 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 21.45 °c. after adding the naoh solution to the coffee cup and stirring the mixed solutions with the thermometer, the maximum temperature measured is 31.50 °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
