2. Heat capacity (C) is:
heat absorbed / increase in temperature heat absorbed / mass of substance increase in temperature / heat absorbed mass of substance / heat absorbed none of the above
3. 500mL of solution A at 23.0°C is mixed with 500mL of solution B in a bomb calorimeter. The final solution has a density of 2.0g/mL, final temperature of 26.3°C, and a specific heat capacity of 5.12 J/°C*g. What is the enthalpy change per mole of the final solution?
