Chapter L.2, Problem 1CYU
Two students measured the freezing point of a sample of pure benzene. Student A used an ordinary laboratory thermometer calibrated in 0.1 ℃ units. Student B used a thermometer certified by NIST (National Institute of Standards and Technology) and calibrated in 0.01 °C units. Their results were as follows:
Student A: 52 °C, 5.7 °C, 5.5 °C, 5.2 °C
Student B: 5.48 °C, 5.52 °C, 5.50 °C, 5.54 °C
Calculate the average value for A and B and, knowing the freezing point of benzene is 5.50 °C (and using kelvins for temperature), calculate the percent error for each student. Which student has the smaller error?

- An environmental chemist working for the Environmental Protection Agency (EPA) was directed to collect razor clams from a heavily-contaminated river superfund site and analyze them for their Ca+ content using graphite furnace atomic absorption spectrometry (GFAAS). The chemist dried the clams at 95 °C overnight and ground them in a scientific blender, resulting in approximately 50 g of homogenized dry weight. A representative 91.79 mg sample was taken from the approximately 50 g of dry material and dissolved in 100.0 ml. of 0.1 M HCI to create a sample solution. Using the method of standard additions, the chemist prepared five standard solutions in 100.0 ml volumetric flasks, cach containing 5.00 ml. aliquots of the sample solution. Varying amounts of a 85.0 ppb (ug/L) Cd+ standard were added to each of the flasks, which were then brought to volume with 0.1 M HCI.
