PRE-LABORATORY QUESTIONS 1. 250.0 mL of a 2.500 M NaOH solution was mixed with 250.0 mL of a 2.500 M HCI ltion in a calorimeter. Both the solutions were at the same temperature initially. Determine the heat of the reaction (kJ/mole), if the temperature goes from 2.0 °C to 48.8 °C. The specific heat of the solution is 4.190 Jlg °C. Assume a density of 1.025 g/mL. KET D 2. 5.00 grams of calcium metal was reacted with 100.0 g of a 2.500 M HCI solution in a coffee cup calorimeter. The temperature went from 20.5 °C to 35.5 °C. Determine the reaction enthalpy per mole of calcium. The specific heat of the solution is 4.180 J/g oC. Assume a solution density of 1.03 g/mL. 215
