When 40.0 ml of 1.00 m h2so4 is added to 80.0 ml of 1.00 m naoh at 20.00°c in a coffee cup calorimeter, the temperature of the aqueous solution increases to 29.20°c. if the mass of the solution is 120.0 g and the specific heat of the calorimeter and solution is 4.184 j/g • °c, how much heat is given off in the reaction? (ignore the mass of the calorimeter in the calculation.) use mc019-1.jpg
