A chemist obtained the following data for the percent compound Z in triplicates (n=3) of an insecticide preparation: 7.47, 6.98, and 7.27. Calculate the 90% confidence limit for the mean of the data assuming that only information about the precision of the method is the precision for the three data points.
A standard solution was prepared containing 10.0 ppm of an analyte and 15.0 ppm of an internal standard. Analysis of the sample gave signals for the analyte and internal standard of 0.155 and 0.233 (arbitrary units), respectively. Sufficient internal standard was added to an unknown sample to make it 15.0 ppm in the internal standard. Analysis of the unknown sample yielded signals for the analyte and internal standard of 0.274 and 0.198, respectively. Calculate the concentration of analyte in the unknown sample.
I need the theoretical molar extinction coefficient of paranitrophenol in mol^-1cm^-1 (using moles not μM). I have to calculate the % difference.At the experimental level it was 7,200 mol^-1cm^-1
Suppose you have 0.01moles of an organic solid in 100ml of water. The partition coefficient P between ether and water is 20. Which results in a greater material recovery-washing the water once with 200ml of ether or twice with 100 ml of ether and combining the two washes? Or is the recovery the same? Be quantitative and show your calculations.

The student was supposed to measure the pH of a 0.1 M hydrochloric acid solution. For this purpose, he used a pH-meter and obtained the following results: 0.90, 0.93, 1.04, 1.02. Present the appropriate graphic and statistical elaboration of the performed analysis and confirm whether the applied pH-meter worked properly.
The absorbance of a 0.5 mM aqueous salicylic acid solution was 0.925. This solution was extracted with 10% ethyl acetate/hexane solution. The absorbance of the extracted aqueous salicylic acid solution at equilibrium was 0.670. Find the equilibrium concentrations of SA in the aqueous and the non-aqueous phases. Calculate the partition coefficient (K) for the salicylic acid.
