In the laboratory you dissolve 19.7g of ammonium lodide in a volumetric flask and add water to a total volume of 500mL. What is the molarity of the solution? M. What is the concentration of the ammonium cation? M. What is the concentration of the iodide anion? M. In the laboratory you dilute 3.52mL of a concentrated 12.0M nitric acid solution to a total volume of 175mL. What is the concentration of the dillute solution? M You wish to make a 0.443M hydrochloric acid solution from a stock solution of 6.00M hydrochloric acid. How much concentrated acid must you add to obtain a total volume of 75.0mL of the dilute solution? In the laboratory, a student dillutes 21.4mL of a 9.54M hydrochloric acid solution to a total volume of 125.0mL. What is the concentration of the dilluted solution? Concentration = How many milliliters of 11.2M hydrochloric acid solution should be used to prepare 5.50L of 0.200MHCl ? mL
