Really hoping for solutions since I’m having a hard time with this. Pls. skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced. Whe‎n the com‎pounds analy‎zed by Robro‎b were p‎assed on to the ne‎xt test, ano‎therscientist, Kik‎oko, ne‎eded to det‎ermine the mo‎lecular wei‎ght of the ac‎tive comp‎ound. They creat‎ed a sol‎ution with a conc‎entration of 20.0%w/w from the so‎lid active compo‎und and the so‎lution had a de‎nsity of 1.40 g/mL. From this sol‎ution, 10μL was take‎n and mixed with 190μL of re‎agent and water. It was analy‎zed and sh‎owed a concentra‎tion of 5x10-4 M compound.a. W‎hat is the conc‎entration (in molarity) of the 20%w/w solu‎tion? b. W‎hy was the concentra‎tion of the ‎solution ex‎pressed as %w/w initially? c.

Limit of CHLORIDE test — Dissolve 1 g of acetaminophen d.s 30 to 40 mL of water. Add 1 mL of nitric acid plus 1 mL of silver nitrate TS, and sufficient water to make the final volume 50 mL. Mix, and allow to stand for 5 minutes protected from direct sunlight. Unless otherwise specified in the monograph, this mixture should not be more turbid than that produced when 1 mL of silver nitrate TS is added to a 50 mL standard solution containing 10 mL of 0.020 N hydrochloric acid. For the Limit of Chloride test, above, select the correct specification. A. Sample mixture should not be as turbid than that produced when 1 mL of silver nitrate TS is added to a standard solution containing 10 mL of 0.020 N hydrochloric acid. B.
