Calorimetry Practice 1. If a 1.45 g sample of iron at 95.0 ˚C is placed into water at 21.6 ˚C , if the final temperature of the water and iron is 26.7 ˚C, what was the mass of the water? The specific heat of iron is 0.11 cal/g ˚C. 2.14 g water

Calorimetry Practice 2. If a sample of silver at 95 ˚C is placed into 127 g of water at 21.6 ˚C , if the final temperature of the water and silver is 24.5 ˚C, what was the mass of the silver ? The specific heat of silver is 0.057 cal/g ˚C. 92 g silver

Calorimetry Practice 4. If a 34.21 g sample of aluminum is placed into 500. g of water at 21.6 ˚C , and the final temperature of the water is 25 ˚C, what was the original temperature of the aluminum? The specific heat of aluminum is 0.21 cal/g ˚C. Initial temp = 261.63 ˚C = 260 ˚C

Calorimetry Practice 5. If a 35.00 g sample of aluminum is placed into 500 g of ethanol at 21.6 ˚C , and the final temperature of the ethanol is 35 ˚C, what was the original temperature of the aluminum? The specific heat of aluminum is 0.21 cal/g ˚C. Specific heat of ethanol is 0.58 cal/g ˚C. Initial temperature = 563.707 ˚C = 600 ˚C

Calorimetry Practice 3. If a sample of silver at 95 ˚C is placed into 127 g of water at 21.6 ˚C , and the final temperature of the water is 22.3 ˚C, what was the mass of the silver? The specific heat of silver is 0.057 cal/g ˚C. 21.45 g silver = 21 g silver
