In a chromatography experiment, a solution containing 0.083 7 M X and 0.066 6 M S gave peak areas of AX = 423 and AS 5 347. (Areas are measured in arbitrary units by the instrument.) To analyze the unknown, 10.0 mL of 0.146 M S were added to 10.0 mL of unknown, and the mixture was diluted to 25.0 mL in a volumetric flask. This mixture gave the chromatogram in Figure 5-8, with peak areas AX = 553 and AS = 582. Find the concentration of X in the unknown.

A student determined fluoride in a toothpaste sample using ion chromatography. A toothpaste sample of mass 0.100 g was dissolved in type I water and then quantitatively filtered through a Whatman #1 filter paper into a clean 100 ml volumetric flask. The flask was then made up to volume with type I water and mixed thoroughly.A portion of the solution was filtered through a 0.45 um filter into a sample vial for analysis. Analysis of the sample gave a fluoride concentration of 1.60 mg/l Calculate the % w/w fluoride in the original toothpaste sample. (Give your answer to 3 decimal places please)
Q3: In a chromatographic analysis, a solution was prepared with 0.0837 M Octane (A) and 0.0666 M nonane (B). Each one produced a peak area of AA = 423 and AB = 347.10.0 ml of 0.146 M nonane was added to 10 ml of an unknown sample, and the sample diluted to 25 ml. The peak areas obtained were AA = 553 and AB = 582. What is the concentration of Octane in the unknown sample?

2. The analytical ability of two lab technicians was compared by having each perform analyses for arsenic using the same method on samples having the same origin. For analyst A, s.d. = 0.12%, N=6; and for analyst B, s.d. = 0.06%, N-5. Do these results suggest a difference in the precision of the two chemists?
Analysis of a chromatogram of a mixture containing 0.0124 M analyte and 0.0448 M standard found that the peak area from the analyte was 324 and that the peak area from the standard was 258. In another experiment, a solution containing an unknown concentration of analyte and 0.0381 M standard was analyzed. The peak area of the analyte was 231, and the peak area of the standard was 197. What is the molar concentration of the unknown?

You are preparing a 100.0 mL standard solution needed for titration analysis. The NaOH (40 g/mol) pellets are measured to be 0.5341 g in a balance with acceptable uncertainty of +0.001 g. Mass of the pellets is recorded after taring the container. The pellets are put in a beaker and added with 50 ml distilled water measured by a graduated cylinder.
