Chapter 1, Problem 1.57P

These organic solvents are used to clean compact discs:

Chapter 1, Problem 1.57P, These organic solvents are used to clean compact discs: (a) If a 15.00mL sample of CD cleaner weighs

(a) If a 15.00 mL sample of CD cleaner weighs 11.775   g  at  20 ° C , which solvent does the sample most likely contain?

(b) The chemist analyzing the cleaner calibrates her equipment and finds that the pipet is accurate to ±0 .02 mL, and the balance is accurate to  ±0 .003 g . Is this equipment precise enough to distinguish between ethanol and isopropanol?

A volumetric calcium analysis on triplicate samples of the blood serum of a patient believed to be suffering from a hyperparathyroid condition produced the following data: mmol Ca/L = 3.55, 3.65, 3.14. What is the 95% confidence interval for the mean of the data, assuming(a) No prior information about the precision of the analysis?(b) s → σ = 0.056 mmol Ca/L?
The physical fitness of athletes is measured by “VO2 max,”which is the maximum volume of oxygen consumed by anindividual during incremental exercise (for example, on atreadmill). An average male has a VO2 max of 45 mL O2>kgbody mass/min, but a world-class male athlete can have a VO2max reading of 88.0 mL O2>kg body mass/min. (a) Calculatethe volume of oxygen, in mL, consumed in 1 hr by an averageman who weighs 185 lbs and has a VO2 max reading of 47.5mL O2>kg body mass/min. (b) If this man lost 20 lb, exercised,and increased his VO2 max to 65.0 mL O2>kg body mass/min,how many mL of oxygen would he consume in 1 hr?
Archimedes, a famous Greek scientist, was given a problem by King Hieron II of Syracuse (Sicily). The king suspected that his crown, which was supposed to be made of pure gold, contained some silver alloy, and he asked Archimedes to prove or disprove his suspicion. (It turned out that the crown did not contain silver.) How would you experimentally determined whether or not the crown was pure gold? (Hint: The method came to Archimedes when getting into a full bathtub. See the footnote in Experiment 22 for Archimedes’ solution.)
