Imagine a newly appointed chemist in the Walgreens you work at has to prepare 200ml of a 0.05M aqueous solution of potassium chloride (KCl). What does he need to measure first to make the solution? Please determine the grams of KCl he needs to prepare the required solution, in case, he asks for your help. After sometime, he comes back to you and says he accidently prepared 200ml of 1 M KCl solution. He would prepare a fresh one based on your calculations but, unfortunately, he used up all the KCl. How would you solve this situation?
