A mass of 35.0 g of an unknown solid initially at 170.0 ∘C is added to an ideal constant-pressure calorimeter containing 100.0 g of water (Cs, water=4.184 J/(g⋅∘C)) initially at 20.0 ∘C. After the mixture reaches thermal equilibrium, the final temperature is recorded to be 38.73 ∘C. What is the specific heat capacity of the unknown solid?
