Final answer:
To calculate the heat of solution, qsoln, the heat absorbed by the calorimeter must be taken into account, which requires knowing the heat capacity of the calorimeter and the temperature change. This is because the heat transferred from or to the calorimeter affects the final temperature observed in a calorimetric experiment.
Step-by-step explanation:
The student is inquiring about how to calculate the heat of solution, qsoln, after taking into account the heat absorbed by both the solution and the calorimeter. To find the correct answer, it's important to consider that the calorimeter has a known heat capacity and that during the process of dissolution, some amount of heat is absorbed by the calorimeter and affects the overall temperature change observed in the experiment. Therefore, the heat of the solution can be calculated by considering the temperature change, the heat capacity, the mass of the solution, and correcting for the heat absorbed by the calorimeter.
If the reaction in a calorimeter releases heat (qrxn < 0), then heat is absorbed by the calorimeter (qcalorimeter > 0) resulting in an increase in temperature. Conversely, if the reaction absorbs heat (qrxn > 0), heat is transferred from the calorimeter (qcalorimeter < 0) resulting in a temperature decrease. The amount of heat absorbed or released by the calorimeter is critical to correctly calculate the heat of the solution.
