Question 1: We have a bomb calorimeter with a heat capacity of 555 J/K. In this bomb, we place 1000.0 mL of water. 2.110 g of a solid are burned in the bomb calorimeter. The temperature 2.17 deg*C of the bomb and water increases by The molar mass of this solid is 538g/m*ol How much heat would be released (in kJ, and note that we want the amount of heat released ) if we burned 0.125 mol of this solid in the bomb calorimeter?
