7. The lead level in a sample of contaminated soil was determined using atomic absorption spectrometry. A 2.0 g sample was dissolved in acid and then diluted to a total volume of 50.0 mL. The absorbance of this solution, determined in a spectrometer set at a wavelength of 218 nm, was found to be 0.20. Several standard solutions of lead were tested under the same conditions and the calibration curve shown below was generated. The concentration of lead in the...

A person's blood alcohol (C2H5OH) level can be determined by titrating a sample of blood plasma with a potassium dichromate solution. The balanced equation is 16H+(aq) + 2Cr2O72−(aq) + C2H5OH(aq) → 4Cr3+(aq) + 2CO2(g) + 11H2O(l) If 35.46 mL of 0.05961 M Cr2O72− is required to titrate 27.30 g of plasma, what is the mass percent of alcohol in the blood?
