To a crucible and cover weighing 33.392 g is added a sample of a copper (II) chloride hydrate (CuCl2 • nH2O). The mass of the crucible, cover and contents is 34.405 g. The hydrate sample was heated until all the water was driven off. Upon cooling, the sample plus crucible and cover weighed 33.881 g. The molar mass of anhydrous CuCl2 is 134.456 g/mol. (a) How many moles of water are in the hydrate? (b) How many moles of anhydrous CuCl2 are in the hydrate? (c) What is the formula of the copper (II) chloride hydrate?

Lead ions can be precipitated from solution with KCl according to the following reaction: Pb2+(aq)+2KCl(aq)→PbCl2(s)+2K+(aq) When 28.6 g KCl is added to a solution containing 25.5 gPb2+, a PbCl2 precipitate forms. The precipitate is filtered and dried and found to have a mass of 29.0 g . Determine the limiting reactant.
Antimony is alloyed with lead to increase the rigidity of components used in the construction of lead storage batteries.1.304 g of a particular metallic alloy, compounded of only Pb and Sb, can be quantitatively converted into a 1.511-g mixture of the oxides PbO2 and Sb2O4.What was the percentage (by mass) of antimony in the alloy?
An iron ore was analyzed by dissolving a 2.9912-g sample in concentrated HCl. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe2O3‧xH2O by the addition of NH3. After filtration and washing, the residue was ignited at a high temperature to give 0.8394 g of pure Fe2O3 (159.69 g/mol).
The stock solution of bromine is prepared by dissolving 7.75 g of Br2 and 6.25 g of KBr in water and diluting to 25.00 mL in a volumetric flask. Calculate the molarity of Br2 in the stock solution. (KBr is present to facilitate the reaction.)
An unknown mass of Na3PO4(s) is dissolved in water to form 50.00 mL of solution. Thisis Solution A. Then 10.00 mL of Solution A is diluted with water to 50.00 mL. The final solution is Solution B. 20.00 mL of Solution B contains 4.408 × 1020 sodium ions. (NA = 6.022 × 1023 mol–1)Calculate the mass of Na3PO4(s) that was dissolved to form Solution A.
A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?

In the experiment, a student is given 2.94 g of a mixture containing anhydrous MgCl2 and KNO3. To determine the percentage by mass of MgCl2 in the mixture, the student uses excess AgNO3(aq) to precipitate the chloride ion as AgCl(s). Starting with the 2.94 g sample of the mixture dissolved in water, briefly describe the steps necessary to quantitatively determine the mass of the AgCl precipitate. The student determines the mass of the AgCl precipitate to be 5.48 g. On the basis of this information, calculate each of the following.(i) The number of moles of MgCl2 in the original mixture (ii) The percent by mass of MgCl2 in the original mixture
