The answer to your question is: Cp = 0.6373 J/g°C
Explanation:
Sample
mass = 245.7 g
T1 = 75°C
T2 = 34°
Cp = ?
Water
Mass = 115.4 g
T1 = 22°C
T2 = 34°
Cp = 4.184 J/g°C
Heat of metal = mCp(T2 - T1) = 245.7Cp (34 - 75) = -9090.9Cp
Heat of water = = 115.4(4.184)(34 - 22) = -5794
Heat of metal = heat of water
-9090.9Cp = -5794
Cp = -5794 / -9090.9
Cp = 0.6373 J/g°C specific heat of metal
