Suppose $39.8\mathrm{g}$ of zinc bromide is dissolved in $300.\mathrm{mL}$ of a $0.60\mathrm{M}$ aquecus solution of potassium carbonate. Calculate the final molarity of bromide anion in the solution. You can assume the velume of the solution doesn't change when the zinc bromide is dissolved in it. Round your answer to 3 significant digits.
