Answer:

119.5 J

Explanation:

First we calculate the temperature difference:

  • ΔT = 100 °C - 50 °C = 50 °C

Then we can calculate the heat released by using the following formula:

  • q = Cp * ΔT * m

Where q is the heat, Cp is the specific heat, ΔT is the temperature difference and m is the mass.

We input the data:

  • q = 0.239 J/g°C * 50 °C * 10.0 g
  • q = 119.5 J
