Suppose 1.94g of sodium bromide is dissolved in 200.mL of a 57.0mM aqueous solution of silver nitrate. Calculate the final molarity of bromide anion in the solution. You can assume the volume of the solution doesn't change when the sodium bromide is dissolved in it.Round your answer to 2 significant digits.
