Suppose 10.9g of iron(II) bromide is dissolved in 100.mL of a 0.80M aqueous solution of silver nitrate. Calculate the final molarity of iron(II) cation in the solution. You can assume the volume of the solution doesn't change when the iron(II) bromide is dissolved in it.Round your answer to 3 significant digits.
