The number of calories in 3.0 g of glucose (blood sugar) is listed as 10.0 cal. If 15.0 g of glucose is reacted in a calorimeter, such that all of the energy is released and captured in a 1,000.00-gram water bath surrounding the calorimeter, what is the expected final temperature of the water following the reaction if the initial water temperature is 21.0°C? The specific heat of water is 4.18 J/g °C or 1.00 cal/g °C. Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter your answer in the text box below.
