Answer:

Q = 4133.2 J

Explanation:

Hello there!

In this case, since these calorimetry problems are based off the following heat equation involving heat (Q), mass (m), specific heat (C) and temperatures (T):

[tex]Q=mC(T_2-T_1)[/tex]

Thus, we plug in the given variables to obtain:

[tex]Q=62.0 g*2.433 \frac{J}{g\°C}* (40.5\°C-13.1\°C)\\\\Q=4133.2J[/tex]

Regards!
