You must show calculations in to receive credit. 1. A 6.245 g sample of a hydrate has a mass loss of 2.525 g upon heating. Calculate the percent water by mass in the hydrate and identify the hydrate using the chart in the laboratory procedure. % water Hydrate 2. A hydrate weighed 8.456 g before heating and after heating the anyhydrous compound weighed 5.725 g. Calculate the percent water by mass in the hydrate and using the chart in the laboratory procedure identify the hydrate. % water Hydrate 3. Using the table on the previous page, calculate the mass loss expected when 25.527 g of CaSO4 2H20 are heated.
