Indicate which of the following are determinate and indeterminate errors. a. A hygroscopic sample is not dried in the oven prior to weighing.b. The burette reading of 28.43 mL is written downs to 28.34 mL.c. The bottom of the meniscus in the burette is estimated to be at the zero-milliliter mark but in fact, is very slightly below this mark.d. The liquid in a 10 mL TD pipet is blown out by mouth.e.

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.

The amounts reported for the monitored ingredients under internal standard calibration are insensitive to illegal dilutions performed to the preparations, once the internal standard substance was in. True False
Chemistry Calculate the mean, standard deviation, coefficient of variation given the following data Initial volume ( 0.00 + 0.05ml) Final volume ( 30.95 + 0.05ml) Discharged volume ( 30.95 + 0.05ml)
To determine the organic material in a dried lake bed, the percent carbon by mass is measured at two different locations. To compare the means of the two different locations, it must first be determined whether the standard deviations of the two locations are different. For each location, calculate the standard deviation and report it with two significant figures. What is the calculated F value for comparing the standard deviations? Are the standard deviations for the two locations significantly different at the 95% confidence level? ample Location 1 (% C) Location 2 (% C) 1 10.40 10.10 2 10.30 10.90 3 10.30 10.20 4 10.40 10.70 5 10.30 10.30

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.
A student weighed approximately 1.5 g of an unknown solid acid and carefully placed the sample in a clean, but not necessarily dry, 250.0 mL volumetric flask. The student added deionized water to the flask, swirled the solution until the solid acid dissolved, then added sufficient deionized water to fill the flask to the fill line. A volumetric pipet was used to transfer 25.00 mL of the resulting solution to an Erlenmeyer flask, and 2 – 3 drops of phenolphthalein were added.The student filled the sodium hydroxide buret and titrated the acid solution with standardized 0.1000 M NaOH to the first permanent faint pink color, then repeated the titration a second time.Your instructor will provide the mass of unknown solid acid, as well as the initial and final buret readings for the two titrations. From this data and the information above, you will be able to calculate the molar mass of the unknown acid.The unknown solid acid is diprotic; that is, there are two moles of ionizable H+ ions per…
