a) In the laboratory you dissolve 14.5 g of chromium(II) bromide
in a volumetric flask and add water to a total volume of 500. mL.
What is the molarity of the solution?
b) In the laboratory, a student adds 56.1 mL of water to 16.1 mL
of a 0.714 M hydroiodic acid solution. What is the concentration of
the diluted solution? Assume the volumes are additive.
c) Calculate the volume of 0.220-M NaOH solution needed to
completely neutralize 28.5 mL...
