a coffe cup calorimetry experiment was performed in a general chemistry class. Two lab partners added 78.9g of lead initally at a temperature of 102.1 degrees celcuis, to a sample of water in a coffee-cup calorimeter. the water in the calorimeter startedout at 22.9 degrees celcuis, once the temperature of the water and the metal equilibrated the final temperature of both was 24.3 degree celcuis. Calculate the mass of water that must have been in their calorimeter. The spefific capacity of silver is 0.190 J/gC and specific heat capacity of water is 4.184 J/gC.

These questions pertain to a lab done on calorimetry. A block of metal was heated in a hot water bath and transferred to styrofoam cup 2/3 full of room temperature water. 1. If the hot metal had been very wet when it was transferred into the calorimeter, how would the experimental value of the specific heat capacity have been changed? Explain. 2. Explain, on an atomic/molecular level, how and why specific heat capacity is specific.

I recently did a lab where we used a Styrofoam coffee cup calorimeter to determine the specific heat of an unknown metal. We just determined our "calorimeter constant." We now have to re-do all of our prior calculations to include this new constant. I may have written down the wrong equation, so could someone show me an example given the following information? Heat capacity of calorimeter: 41.6 J/gC Mass of metal: 43.0760g Mass of water: 20.6314g Delta T water: 21.1...

Enter your answer in the provided box. When 22.9 mL of 0.500 M H2SO4 is added to 22.9 mL of 1.00 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17 °C. Calculate ΔH of this reaction. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water.) (d for water = 1.00 g/mL; c for water =...

A coffee-cup calorimeter initially contains 125 g water at 24.2 degrees celsius. Ammonium Nitrate (10.5 g), also at 24.2 degree celsius, is added to the water, and after the ammonium nitrate dissolves, the final temperature is 18.3 degrees celsius.What is the heat of solution of ammonium nitrate in kj/mol? Assume that the specific heat capacity of the solution is 4.18 J/Cg and that no heat is transferred to the surrounds or to the calorimeter.

two parts for one question ----------------------------------------- In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant. One way to do this is...

19. How much heat is liberated (in kJ) from 2.47E+2 g of silver when it cools from 8.86E+1 °C to 2.57E+1 °C? The heat capacity of silver is 0.235 J g^{-1} °C^{-1} g−1°C−1. Note, "heat liberated" implies that the change in heat is negative. Enter a positive number 20. A sample of sand initially at 2.18E+1 °C absorbs 1.386E+3 J of heat.
