Question 34 (8 points) A 50.0 g sample of H20 at 100.00°C was placed in an insulated cup. Then 25.3 g of a metal at 25.00°C was added to the water. The temperature of the water dropped to 96.68°C. What is the specific heat of the metal in J/g°C? The specific heat of water is 4.184 J/g°C. Assume that the heat absorbed by the cup is negligible. Please report your answer to the correct number of significant...
