2. A student was asked to identify a sample of unknown hydrate. Student was provided with the following experimental data. 3.51 g sample of the hydrate when heated loses water completely and the mass of the residue was found to be 2.22 g. Student was provided with two reference compounds from which student needs to identify the unknown: Cu(NO3)2. 3H2O and Cu(NO3)2. 6H20. Answer the followings. a. Calculate percent water of hydration in the sample. (show your calculations)
You are given a sample that contains a mixture of the following two arsenic-containing minerals: gersdorffite (NiAsS) and getchellite (AsSbS3). You start with a sample of this mixture that has a mass of 57.38 grams. You perform a reaction that converts the arsenic (As) in these minerals into the form arsenic(V) oxide (As2O5), and 36.03 grams of this product are obtained.What is the percent by mass of gersdorffite in the original sample? Please, give all your calculations with three significant figures.
Consider a 134.5 g sample of the compound manganese(IV) perchlorate. Using the formula Mn(ClO₄)₄ (MM = 452.74), what is the percent by mass of Mn in the compound?
Quinine is the bitter-tasting compound in tonic water. Quinine is also used to prevent malaria. The chemical formula of quinine is C20H24N2O2. If you burn a 0.895 g sample of quinine in excess oxygen, how many grams of carbon dioxide would you obtain?
Calculate the mass (in grams) of 4.54 × 1020 molecules of hydroxychloroquine, C18H26ClN3O. Report your answer to 4 decimal places.
Compound Z is a chemical naturally found in peppermint and other mint plants and has mild anesthetic properties. In a combustion analysis experiment, 95.6 mg of Compound Z (molar mass = 156 g/mol) are burned in oxygen gas to give 269 mg CO2 and 110 mg H20. What is Compound Z's empirical formula? Write the numbers that you would write in the subscript of the formula in the boxes next to the symbol of the element. If the subscript is 1, type 1 although you normally would not write 1 in the formula. H.
A molecular formula expresses the number of each kind of atom in a molecule. For example, the molecular formula for propene, C3H6C3H6, indicates three carbon atoms and six hydrogen atoms per molecule. This also means that one mole of propene contains three moles of carbon and six moles of hydrogen.An empirical formula expresses the mole ratio of the elements. The empirical formula for propene is CH2CH2, indicating twice as much hydrogen as carbon. When analyzing unknown compounds in a lab, it is often possible to identify the mole ratios, and thus the empirical formula, but not the molecular formula.Notice that the molecular mass of propene, 3(12)+6(1)=42amu3(12)+6(1)=42amu, is a multiple of the empirical formula mass, 1(12)+2(1)=14 amu An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOzCxHyOz).

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?
