A 2.914-g sample of gypsum, a hydrated salt of calcium sulfate, CaSO4, is heated at a temperature greater than 170 Celsius in a crucible until a constant mass is reached. The mass of the anhydrous CaSO4 salt is 2.304 g. Calculate the percent by mass of water in the hydrated calcium sulfate salt. Calculate the moles of water removed and the moles of anhydrous CaSO4 reamaining in the crucible.
