A 5.85 g sample of a salt with a molar mass of 84.10 g/mol is added to a calorimeter containing 53.51 g of deionized water. The initial temperature of the water is 21.68°C; the final temperature of the solution is 18.97°C. Assume the specific heat of the solution is the same as pure water, 4.184 J/g°C. Pre-Lab Hints. Explain how the temperature of the metal and the water bath become equalized, and how that final equalized temperature is measured. Heat loss causes a lower Tf. Examine Figure 25.5 and read the label over the line to see the overall effect on Tf.
