A laboratory technician is preparing a stock solution of KOH for use in some General Chemistry lab classes. The technician dissolves 143.4 grams of NaOH in water to make 750.0 mL of stock solution. Once in the lab class, students take 23.85 mL of this stock solution and dilute it to a final volume of 200.0 mL before using this solution for their experiment. What is the concentration of KOH in the final solution that the students use?
