Answer:
39.1 °C
Explanation:
Recall the equation for specific heat:

Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.
You should know that the specific heat of water is 1 cal/g/C.
Using the information in the question:

The final temperature is about 39.1 °C.
