How many milligrams of painkiller should presented every 4-6 h?A forensic chemist prepares a standard of caffeine in chloroform for use in a quantitative assay. The caffeine is purchased from a reputable supply company and arrives with a certificate stating that it is 99.5% pure or better (written 99.5% + or + 99.5%). The analyst needs to make a stock solution at a concentration near 1 mg/mL. To do so, she obtains a Class A 50.00 mL volumetric flask (± 0.05 mL) and uses an analytical balance to accurately weight out 49.6 mg. The balance uncertainty is listed as ± 0.0003 g near the 50 mg range. The analyst quantitatively transfers the powder to the flask and carefully dilutes the solution to volume. Report the concentration of the solution in mg/mL and the propagated uncertainty associated with it. Use the NUSAP form to report your answer with the proper number of significant figures in the final result. You get to pick which “assessment” is presented.
