3 4 5 6 8 9 10 (5) final temperature of calorimater water: 26°C ===== Given this information, determine how many calories per gram are contained in this hypotheti food (small calories). ==== 0 + 41.0 calories I gram 0+ 48.0 calories I gram 0-52.0 calories I gram 0455.0 calories I gram +62.0 calories I gram

Note: S.H.water = 1.0 calorie (1.0 gram x 1.0°C) Note: 1 (large) CALORIE = 1,000 (small) calories (1) weight of food materal: 21.8 grams (2) weight of water in calorimeter: 200 grams (3) weight of styrofoam coffee cup: 25 grams (4) initial temperature of calorimater water: 20°C (5) final temperature of calorimater water: 26°C ==== Given this information, determine how many calories per gram are contained in this hypot food (small calories).

Experiment #8: Question #2 - Estimating the Calorie Content of Nuts (5 points) When calorimetry is done for a large number of foods, we can decide which foc eat and which to avoid to manage our weight. The goal of this experiment was to determine the caloric content (Calories per gram) for a Planter's peanut. It is clear that calorimetry works on the basis of transferring the heat released by the food to a water reservoir. We calculate that energy (Isoln = msoln * S.H.soln X ATsoln ) from a knowledge of: (1) the change in temperature of the water - ATsoln (2) the mass of the water that was heated - msoln (3) a knowledge how well water stores heat - called the specific heat constant - S.H.water
