1 10 Calorimetry of an unknown metal Reset the simulation and select unknown metal II. Place 50.0 g of unknown metal II into the calorimeter at a temperature of 170 C. . . Use 100 grams of water at 20 C. Click the start button to allow the piece of unknown metal and water to reach equilibrium. 11. Fill out the table below using the information from the experiment: (2 points per blank) DATA Mass of the unknown metal II 50 g Initial temperature of the unknown metal II 170 C Mass of the water 100 g Initial temperature of the water 20 ' C Final temperature of the water 22.260 Specific heat of water 9.184 Data Analysis Questions: (7 points each) 12. Use the formula, qwater = MwaterCs,waterATwater, to calculate the amount of heat absorbed by the water. Given: Cs,water = 4.184 J/goc 9 = ( 100) ( 4.184) ( 22.26-20) 9= 946 ( rounded to whole number ) 13. How much heat was released by the metal if qwater = -qmetal? 9 = - qmetal = - (946)170gmetal= - 946 14. Use the information found in question 13 and the formula, qmetal = MmetalCs,metal Tmetal, to calculate the specific heat of the metal. Assume the metal reaches the same temperature as the water . - 946 = (50) (C ) ( 22.26 - 20) 15. Based on your calculated value for Cs and the values in the table of Metal Cs (J/g.C) specific heat for metals, what is the identity of Unknown II? Fe 0.45 Sn 0.21 Ag 0.24 Pb 0.13 Al 0.89
