Question

4. For each error below, detenime now circle the appropriate letter. the reported percent of water and H - means the reported percent of water is Higher because of the error. L - means the reported percent of water is Lower because of the error. N - means the reported percent of water is Not affected by the error. a. Some solid material spattered out of the beaker during the heating in step 3. b. The beaker was wet in step 1 when its mass was determined. c. The beaker and anhydrous solid were carried in wet hands over to the balance for the final weighing. d. The substance was heated so strongly that some of anhydrous salt was vaporized. e. There was a mechanical defect in the balance so that all masses reading were 1.0 g too high.
