4. You placed 43.1 g of an unknown metal at 100 °C into a coffee cup calorimeter that contained 50.0 g of water that was initially at 22.0 °C. The equilibrium temperature of mixing (T0) was determined to be 23.7 °C. The calorimeter constant was known to be 51.5 J/°C. Specific HeatH2O = 4.184 J/g·°C a. What is the total amount of heat (J) lost by the metal? NG 1.5 b. What was the specific heat (J/g·°C) of the metal?...
A piece of copper metal is initially at 83.0°C. It is dropped into a coffee cup calorimeter containing 30.0 9 of water at a temperature of 10.0°c. After stirring, the final temperature of both copper and water is 25.0°c. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g.), what is the heat capacity of the copper in J/K?
A 83.5 g sample of a metal alloy is heated to 88.1oC and it is then placed in a coffee-cup calorimeter containing 30.0 g water at 15.0oC. The final temperature of the metal + water is 25.3 oC. Calculate the specific heat of metal alloy, in J/(g oC), assuming no heat escapes to the surroundings or is transferred to the calorimeter. The specific heat of water is 4.184 J/(g oC).
21.A piece of copper metal is initially at 100 C. It is dropped into a coffee cup calorimeter containing 50.0g of water at a temperature of 20.0°C.

5. (2) The coffee cup calorimeter, although a good insulator, does absorb some heat during each experiment. If a calorimeter constant is not determined, how would this affect the specific heat of the metal? Be specific. 6. (3) An unknown metal weighing 13.11 g at a temperature of 81.0 °C is place in a calorimeter containing 25.0 mL of water at a temperature of 25.0 °C. The final equilibrium temperature is 30.0 °C. What is the specific heat of the...
A piece of metal weighing 6.00 g at a temperature of 33.5 oC was placed in a calorimeter in 20.05 mL of water at 19.0 oC . The final equilibrium temperature was found to be 25.9 oC . What is the specific heat of the metal?
In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.4 grams of gold to 97.94°C and then drops it into a cup containing 81.9 grams of water at 24.30°C. She measures the final temperature to be 24.85°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of gold to be_______ J/g°C.
9. A 48.8 g piece of an unknown metal was heated to 99.8°C, then dropped into a coffee cup calorimeter containing 40.0 g of water at 26.3°C The temperature of the water increased to 30.2°C. How much heat flowed into the water? What is the specific heat of the unknown metal?
