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...

6
7-2: Standardization of a Permanganate Solution of Titrations provide a method of quantitatively measuring the concentration of an unknown solution. This is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) In oxidation-reduction (redox) titrations, the voltage resulting from the mixture of an oxidant...
