Hi plz q7
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.
Solve correctly please.
ATES OF MATTER Solving applied mass concentration problems GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved triiodothyronine (230. to 660. pg/dL), using a blood sample that is as small as 150 µL. Calculate the minimum mass in picograms of triiodothyronine that the new system must be able to detect. Be sure your answer has the correct number of significant digits. Pg X 3/5 S

You are in the lab preparing copper solutions for the MICRO lab this week. You measure 0.1035 (±0.0001) g of copper metal and dissolve it in a few mLs of concentrated nitric acid. This solution is diluted to the mark with water in a 50.00 (±0.05) mL volumetric flask. You withdraw a 5.00 (±0.01) mL aliquot with a volumetric pipet and deliver it to a 100.00 (±0.08) mL volumetric flask. After dilution to the mark with water, calculate the concentration and the absolute error in a solution of copper in ppm (assume ppm = 1 µg/g = 1 µg/mL = 1 mg/L).
