An experimenter created a solution with a concentration of 20.0%(w/w) from a solid active compound and the solution had a density of 1.4g/mL. From this solution, 10µL was withdrawn and mixed w/ 190µL of reagent & water. It manifested a concentration of 5x10 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?
