A solution is made by dissolving 21.2g of sodium hydroxide, NaOH, in enough water to make exactly 100. mL of solution. Calculate the molarity of each species: NaOHNa+OHmol/Lmol/Lmol/L A stock solution of CoCl2 is available to prepare solutions that are more dilute. Calculate the volume, in mL, of a 2.0-M solution of CoCl2 required to prepare exactly 500mL of a 0.270M solution of CoCl2. 5how Approach Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of chromium(III) acetate and barium sulfide are combined. Be sure to specify states such as (aq) or (s). If a box is not needed leave it blank
