Sally obtains a standard calibration curve for their assigned food dye by plotting absorbance versus concentration (in M) of known solutions and finds the following slope and intercept: y = 1.585x + 0.041 Sally finds that her original Kool-aid sample is too concentrated, so they dilute it by transferring 4.00 mL of the original Kool-aid sample into a new container and diluting to a total volume of 27.00 mL. If the absorbance of the dilute Kool-aid sample at the appropriate wavelength for their assigned dye is 0.931, determine the concentration (in M) of the assigned food dye in the original Kool-aid sample. Report your answer with three places after the decimal.

A 1.900-g sample is analyzed for benzoic acid content. The sample was dissolved and diluted to the mark using a 500-mL volumetric flask. A 30.0mL aliquot required 5.00mL of 0.1575M NaOH solution. Calculate the %(w/w) benzoic acid (Fwt=122) in the sample. C6H5COOH + NaOH -------------> C6H5COONa + HOH
A solution prepared by dissolving 25.8 mg of benzene (C6H6, FM 78.11) in hexane and diluting to 250.0 mL has an absorption peak at 256 nm, with an absorbance of 0.266 in a 1.000-cm cell. Hexane does not absorb at 256 nm. Find the molar absorptivity of benzene at this wavelength.
