Fill in the columns of the data table. Be sure to show calculations where they are called for, and to include the correct units for each entry. Mass of calorimeter cups empty Mass of calorimeter cups + 50. mL of d. H₂O Mass of cool water in cups (show calculation) Initial temperature of cool water Initial temperature of heated water prior to mixing Final temperature of combined water samples Mass of calorimeter cups plus combined water samples Mass of heated water used; show calculation. AT for cool water (AT=Tinal-Tinitial); show calculation.) AT for heated water (AT= Tfinal - Tinitial; show calculation.) 3.69 g 53.22 g 21.6°C 63.4°C 40.5°C 100.54 g Part B Calculations. 1) Use Equation 1 (first page) to calculate the quantity of heat absorbed by the cool water. Show your work in the space below and be certain to include units. 2) Calculate the quantity of heat lost by the heated water, again using Equation 1. Show your work in the space below and be certain to include units. Note that this is a negative quantity. 3) Add your answers to questions 1) and 2). Is the total positive, negative, or zero? In other words, was more heat released by the warm water than was absorbed by the cool water, or were the two quantities equal? Suggest an explanation for the result you obtained. 4) Determine the heat capacity of the calorimeter by dividing the difference from question 3) by the rise in temperature by the cool water. Your answer should be expressed in Note that mass is not involved here. "C Fill in the columns of the data table.
