Page |i Jn DATE: DATA SHEET FOR PART A. TRIAL 1 TRIAL 2 1. Mass of the empty beaker and the watch glass: 43.15 3.95 2. Mass of the beaker, watch glass, and hydrate: 195. 959 3. Mass of hydrate: 00 g (ine 2) - (line 1) 4. Mass of the anhydrous salt, beaker, and the5.33 watch glass after the first heating: 2 5. Mass of the anhydrous salt, beaker, and the watch glass after the second heating: 0. 6. Mass of the water: (line 2) - (line 5) 35 % 9 7. Percent of water in the hydrate: [(line 6)/(line 3)] x 100 8. Average percent of water in the hydrate: 9. Compare (line 8) to the correct value of 36.1%. Percent Error- Your value 36.1 36.1 Note: If the percent water is too low, you can heat one more time.

The experiment was all about hydration
