The total number of joules of heat that must be absorbed is 5004 J
Data obtained from the question
From the question given above, the following data were obtained:
- Heat of fusion (Hf) = 333.6 J/g
- Mass (m) = 15 g
How to determine the heat
The heat that must be absorbed by the sample to change it from solid to liquid at its melting point can be obtained as follow:
Q = m × Hf
Q = 15 × 333.6
Q = 5004 J
Thus, 5004 J of heat must be absorbed.
