Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Suppose a pulsar rotates once every 1.743 206 448 872 75 ± 2 ms, where the trailing ± 2 indicates the uncertainty in the last decimal place (it does not mean ± 2 ms).

How many rotation does the pulsar make in 14.0 days?
(b) How much time does the pulsar take to rotate exactly one million times? (Give your answer to at least 4 decimal places.)

(c) What is the associated uncertainty?

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...
