Explain the empty calorimeter has a heat capacity

Reference no: EM13537577

A student takes .05 moles of HCl and reacts it with .05 moles of sodium hydroxide in 100g of water solution in a styrofoam cup calorimeter. The empty calorimeter has a heat capacity of 0J/oC, and the temperature changed from 21.0 oC to 27.5 oC. Calculate the heat of reaction for the sample (kJ). Then calculate the heat of the above reaction in kJ/mol of HCl.
