Casey is completing an experiment that requires a 300 mL solution with a 20% concentration of potassium chloride (KCl). But Casey's lab only stores potassium chloride at concentrations of 10% and 50%. How much 10% KCl solution will Casey have to mix with 50% KCl solution to make 300 mL of 20% KCl solution? A. 30 mL B. 75 mL C. 225 mL D. 300 mL
