Mass of aluminum 16.27 g Initial temperature of Al 83.85°C Volume of water 52.4 mL Initial temperature of water 20.30°C Final water temperature 23.90°C g 1.00 mL Density of water J 4.184 g• °C Specific heat of water J 22.44 °C Calorimeter constant A student adds a heated sample of pure aluminum metal to a Styrofoam coffee cup calorimeter containing deionized water. Use the collected data to answer the following questions. (a) Assuming that heat was transferred from the aluminum to the water and the calorimeter, determine the specific heat of aluminum. J Specific heat of Al = g· °C (b) The actual specific heat of aluminum is 0.900 J Calculate the percent error for the g· °C' experimentally determined specific heat. Percent error = %
