Answer:
The answer to your question is: Cp = 350.4 J/ kg°C
Explanation:
Data
mass = m = 4.7 g convert grams to kilograms 0.0047 kg
heat= Q = 52.7 J
Temperature = 25 - 57 °C
Formula
Q = mCpΔT solve for Cp
Cp = Q / mΔT
Process
Cp = 52.7 / [(0.0047)(57 - 25)] Substitution
Cp = 52.7 / 0.1504
Cp = 350.4 J/ kg°C
