A constant pressure "coffee-cup" calorimeter is used to measure the heat of reaction between 0.10 L of 1.0 M NaOH and 0.10 L of 1.0 M HCI. Both solutions initially are at 24.0°C; after the solutions are mixed, the final temperature is 30.4°C.

Assume the density of all solutions is 1.0 g/mL. (C = 75.291 J/mol•K for H20; q = CcalAT) 270 kJ/mol 5.4 kJ/mol 22 kJ/mol 123 kJ/mol 54 kJ/mol
