Suppose 30.6 g of potassium chloride is dissolved in 150.mL of a 0.80M aqueous solution of silver nitrate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the potassium chloride is dissolved in it.Round your answer to 2 significant digits.
