State the final temperature of the water in the calorimeter

Reference no: EM13251373

A student needs to calibrate a coffee-cup calorimeter. To do so she places 100.0g of water at 58.60C into the calorimeter which already contains 100.0g of water at 19.30C. The final temperature of the water in the calorimeter is 38.70C. What is the heat capacity of the calorimeter?

The calorimeter is then emptied and 345.00ml of water at 21.5000C is then added to it. Then 2.00ml of 6.50M NaOH and 3.00ml of 5.00M acetic acid at the same temperature are added to the calorimeter. The temperature of the solution rises to 26.2180C. The density of the resulting solution is 1.02g/ml. What is ?H (J/mol rxn) for the reaction
