Atomic absorption spectrometry was used with the method of
standard additions to determine the concentration of cadmium in a
sample of an industrial waste stream. For the addition, 10.0 μL of
a 1000.0 μg/mL Cd standard was added to 10.0 mL of solution. The
following data were obtained: Absorbance of reagent blank = 0.041
Absorbance of sample = 0.476 Absorbance of sample plus addition =
0.821 What was the concentration of the cadmium in the waste stream
sample?Later, the analyst...

9. Physicians inform their patients of the total cholesterol
concentration in the blood, but the HDL:LDL cholesterol ratio is
also reported to the patient. Why is the HDL:LDL cholesterol ratio
more informative? Which is more desirable, a high HDL:LDL
cholesterol ratio or a low ratio?

incubation period, the concentration of unbound receptors was
determined to be 15 mM. What is the Kd for the receptor-ligand
interaction?
A) 28 mM
B) 43 mM
C) 143 mM
D) 217 mM
E) 333 mM

Assume you have a sample of DEET that is contaminated by
m-toluic acid. Propose a method to remove the impurity,
explaining how that would work.

2. A new method is developed to determine the content of sodium
in a biscuit sample. Student A gets the following results: 24.2,
23.9, 25.0, 23.7 and 25.2 mg, while student B obtains 22.6, 21.9,
23.2 and 23.1 mg.
(a) Report 95% confidence interval of their results
individually. Why the standard deviations are non-zero?
(b) At the 95% confidence level, does one of them get more
reproducible measurements?
(c) At the 95% confidence level, do they obtain different
results? What...
