Suppose 29.0g of sodium chloride is dissolved in 250.mL of a 0.70M aqueous solution of potassium carbonate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the sodium chloride is dissolved in it. Round your answer to 3 significant digits.
