If 2.500 g of Mg is burned in a constant volume calorimeter with a heat capacity of 1.10 kJ/degrees Celsius containing 1.500 L of water at 23.50 degrees Celsius and releases 37.33 kJ of heat, what is the final temperature of the calorimeter and water?

Please show your work and solve. Thank you.

#### Solution Preview

We know that heat gained = heat lost and so

q(mg burned)=q(calorimeter) + q (water)

q mg released is 37.33 KJ.

So we can then say that -37.33KJ = mcDT(H2O) + mcDT(calorimeter) note that DT is delta temperature)

We have the volume of the water, which ...
