Aoife studies a culture flask of microorganisms. The culture flask has a total volume of 1,000 mL. Every day she takes a 50-mL sample and replaces the volume with sterile media so the total volume in the flask remains the same. After 3 days, what percent of original culture remains? When performing the math, don't forget that every sampling event counts as a dilution. Perform all calculations in a single step using Excel to avoid accumulating rounding error. Report your answer to 2 decimal places.

Classify whether the following is an Instrumental error, Method error, Personal error, Indeterminate error or Gross error and explain. A group of students are doing an analysis of copper in 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. Marikit had very good precision but poor accuracy in her data. Volumetric flasks were placed inside the oven for drying before it was used. Trial 1 and 2 have values close to 30.0 mL while trial 3 gave 55.0 mL. The reagent used in determining copper was added incorrectly and gave a low yield.

Preparation of 0.25N NaOH Objective: Apparatus and Materials: Procedure : Calculate the exact mass of NaOH needed to prepare 1.0L of 0.25N NaOH for standardization. Show your computations. Using the triple beam balance, weigh the desired amount of NaOH. Place the weighed amount of NaOH into the 500 mL volumetric flask and add distilled water until it reaches the mark. Agitate and transfer the solution into the reagent bottle. Add again distilled water to the same volumetric flask until it reaches the mark and pour it to the same reagent bottle, thus having a total volume of 1.0 L. Label the reagent bottle, 0.25N NaOH. Data and Computations: Conclusion:
Explain the use of plans and their importance in assessing the quality of pharmaceutical products. Provide a step-by-step design of a sampling plan based on a normal inspection for a 75,000 tablets with an AQL of 0.12% using the attached table (at the end of exam paper).
Chemistry The levels of an organic pollutant (P) in the groundwater at the perimeter of a plant were a cause for concern. A 10 mL sample of the water was taken and the pollutant was extracted with 95% efficiency using 25 mL of diethyl ether. GC was used to analyse the concentration of P in diethyl ether. A calibration curve was plotted for a series of standards of P which yielded the following results: Peak Area Toluene Conc. (µg/ml) 12,000 2.6 23,700 5.0 35,500 7.7 46,800 9.9 31,250 Sample Determine the concentration of P in ppb in the initial groundwater sample.
You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Often the analyst will compare known quantities of analyte to unknown quantities of the material to be analyzed. This may be done in one of three ways: -use calibration curves; use standard additions; or use internal standards. The method of standard additions would be used when A) the quantity of sample analyzed or the instrument response varies from run to run. B) the standard solutions and the unknown solution all have similar characteristics are unaffected by the other material in the sample. C) the sample composition is unknown or complex and affects the analytical signal.
