Two ways the concentration of a solution can be reported are: 1) mass % and 2) molarity. The reagent bottle of concentrated HCl used in Exp. 5 gave a mass percent in the 36.5 – 38% (w/w) range. a.What is the mass % HCl of a 1.00 M HCl (aq) solution? The density of this solution is 1.02 g/mL. b. What volume of 1.00 M HCl would you measure to prepare a 0.300 M HCl solution in a 250-mL volumetric flask? c.Which piece of equipment from the lab drawer should be used to measure this volume to the appropriate degree of accuracy? Explain your reasoning.i.100-mL beaker with graduated markings every 25 mLii.100-mL graduated cylinder with graduated markings every 1
