When 0.0200 L of 0.800 M NaOH is mixed with 0.0400 L of 0.400 M HNO3 in a coffee-cup calorimeter, the temperature rises from 18.88°C to 21.29°C. The heat capacity of the calorimeter apparatus is 108 J/K. Calculate AH (in J) for the reaction: NaOH(aq) + HNO3(aq) → NaNO3(aq) + H2O(1) Assume the total volume of the solution mixture is 0.0600 L with a specific heat capacity of 4.18 J/K-g and the density of 1.05 g/mL. Discussion: Why is AH rather than AU determined by coffee-cup calorimetry? When doing a coffee cup calorimetry experiment, the heat generated or absorbed from the chemical reaction is transferred to the calorimeter apparatus including the thermometer. Thus, what would be the sign (positive or negative) AH if there is an increase in temperature? Since heat flow is related to the amount of solution in grams now can you determine the amount of solution in grams using the volume of NaOH and HNO3? Wha he heat capacity of the calorimeter apparatus?
