Ammonium perchlorate NH4ClO4 is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N2 gas, chlorine Cl2 gas, oxygen O2 gas and water vapor, releasing a great deal of energy. Calculate the moles of oxygen produced by the reaction of 0.075mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

How many molecules of hydrogen fluoride (HF) are in (2.1x10^-2) moles of hydrogen fluoride (HF)? For Avogadro's number use: 6.022 x 1023 Round your answer to two significant figures. For the unit, use the word molecule. Note: Your answer is assumed to be reduced to the highest power possible.
High fructose corn syrup (HFCS) is a sweetener that was designed in the 1970s, which takes corn starch and chemically modifies it to have a mixture of the constitutional isomers glucose and fructose (both of the formula C6H12O6). HFCS 55 is the type found in US sodas (like Coca Cola) and it contains 55.1% fructose molecules and 44.9% glucose molecules. Given that information, calculate how many molecules of fructose would be found in a can of coca cola if the amount of HFCS used were 67.5 g? Use the correct number of significant figures. *Input answer as: 6.022x10^23

The following data were obtained when a test tube containing barium chloride hydrate was weighed before and after heating. The heating process drove off the water that was in the sample, producing an anhydrous salt. a) Mass of an empty test tube = 18.42g b) Mass of the test tube containing hydrate (before heating) = 20.75; c) Mass of the test tube containing anhydrous salt (after heating) = 20.41g The general formula of barium chloride is BaCl2 · nH2O, where n is the number of water molecules. The hydrate described by the data above either has a value of n=1; n=2; or n =3. Calculate the mass percent of water for each of these possible values of n
