6. A volatilization gravimetry experiment was conducted on an unknown organic liquid (presumed to only contain carbon, hydrogen, and oxygen). The liquid was massed (data in the first column below) and then combusted in an excess of oxygen. The exhaust gas was passed through a trap containing drierite and then through a trap containing ascarite. The starting and ending masses of the drierite and ascarite were used to obtain the data in the second two columns below. Mass Unknown 12.4370 12.5590 12.2230 Mass CO2 17.0822 17.2497 16.7882 Mass H₂O 13.9849 14.1221 13.7443 A.) Calculate the mass percent of carbon, hydrogen, and oxygen in the unknown liquid. There are no outliers, so you can average the data before processing, if you wish. B.) Calculate the empirical formula of the unknown compound.

One of the most important reactions in biology is photosynthesis. In this complex chemical process, plants combine molecules of carbon dioxide and water to create glucose and oxygen. The reaction looks something like this: CO2 + H20 – C6H1206 + 02 Of course the number of atoms don't balance on the two sides. You might be able to intuit your way to the correct counting (stoichiometry), but let's do it systematically by setting up equations. (a) Write the reaction as a CO2 + b H20 -→ c CGH1206 + d O2 where a, b, c, and d are meant to be integers adjusted so that the number of each kind of atoms balance on each side. For this reaction, we have three kinds of atoms that must balance: carbon (C), hydrogen (H), and oxygen (0). Write three equations for a, b, c, and d that, if satisfied, will guarantee that the number of atoms of each kind are the same on each side of the reaction. (b) Find the smallest set of integers that will satisfy these equations. First, solve for a. (c) Solve for b.

Fluoride determination can be performed photometrically with alizarin red and Zirconium acid solution, obtaining the following data in the calibration: (View Table) 100.0 mL of well water are measured and concentrated to 50 ml by evaporation, the alizarin and zirconium reagents are added (in quantity proportional to the standards) and after the appropriate time, the reading of the instrument (under the same conditions instrumental) reports an absorbance of 0.182. How much fluoride in mg / L does the well water sample contain?
