Tip: to find the unknown number of water molecules in a hydrate, you need the percentage composition of the anhydrous compound of the water. 1. TA Calculate the percent by mass of water in CoCl₂ 6 H₂O(s). 2. TA A 75.0 g sample of Na,SO, xH₂O(s) contains 33.1 g of Na₂SO,(s). Calculate the percent by mass of water and the final value of x in Na.SO, xH₂O(s). 3. T Determine the formula for the hydrate of aluminum chloride that is 44.8% water by mass. 4. T Determine the formula for the hydrate of magnesium bromide that is 37.0% water by mass. 5. TA sample of a hydrate of lithium chloride is 5.235 g. It is heated until it is an anhydride and its mass is 2.300 g. Determine the formula for the hydrate. 6. TI A hydrate of barium perchlorate, Ba(CIO), xH₂O, contains 35.2% of barium by mass. Find the value of x.
