Document Summary
Chem 2080: lab 1 ice fisherman"s friend. The new product, ice fisherman"s friend, is not feasible given the stated weight and volume restrictions. The weight of the new product is 282. 833 grams, which is about 0. 62 pounds of cacl2 and slightly over the limit of 0. 5 pounds. Its volume, 131. 55 ml, is also much larger than the volume of a deck of cards, which is approximately 88 ml. The unknown salt determination experiment revealed that the unknown salt should be lithium chloride. The unknown salt, labeled, salt of beauty, was obtained a weighed to be. 4. 929 g. the salt was stirred in a calorimeter filled with 50 ml of water. The temperature was recorded until stabilized, and this experiment was repeated for three trials. The heat capacity of the solid part of the calorimeter, cp, sol, was calculated to be 85. 77 j/ .
