A 1.803-g sample of gypsum, a hydrated salt of calciumsulfate, CaSO4, is heated in a crucible until a constantmass is reached. The mass of the anhydrous CaSO4 salt is1.426-g. Calculate the percent by mass of water in the hydratedcalcium sulfate salt. Also, calculate the moles of water removedand the moles of anhydrous CaSO4 remaining in thecrucible. And, finally, What is the formula of the hydrated calciumsulfate; that is, what is the whole-number mole ratio of calciumsulfate to water? Please show...
