A 45.90 g sample of pure copper is heated in a test tube to 99.40°C. The copper sample is then transferred to a calorimeter containing 61.04 g of deionized water. The water temperature in the calorimeter rises from 24.47°C to 29.10°C. The specific heat capacity of copper metal and water are J J 0.387 and 4.184 respectively. g•°C g.°C' Assuming that heat was transferred from the copper to the water and the calorimeter, determine the heat capacity of the calorimeter....
