A student doing a calorimetry experiment similar to this one is asked to find the calorimeter constant for the calorimeter he is using. Cold water i measured. Water is heated on a hot plate. The temperature is measured. Some hot water is added to the taken along the way. The data is given below s added to the calorimeter, the temperature is calorimeter with the cold water. The final temperature is measured The masses . are Trial 2 25.4361g 50.1938g 50.2011g 20.1°C 85.6°C Trial 3 25.6738 Trial 1 Mass of empty calorimeter: Mass calorimeter with cold water 25.4356 0.1927g - 19.9°C 90.2°C Temperature of cold water in calorimeter 19.7°C Temperature of hot water Mass of calorimeter with hot and cold 75.2201g water mixture 83.5°C 74.3392g 75.0 680g Final temperature of water mixture 48.9 Use the data given above to calculate the calorimeter constant including the average and standard deviation. Be sure to give correct units and significant figures. As always, work must be shown to receive credit. 62
