PROCEDURE 1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat sheet. 2. Obtain your medicine tablet. Take note of its mass. [Note: Since this is home experiment and that you might not have a weighing scale at home, assume that given mass of the tablet is pure, with any excipient/(s). For example, a 500 mg ascorbic acid will have a mass of 500 mg as indicated.] 3. Pulverize the tablet into fine powder and trransfer it in a clean and dry vessel or bottle. 5. Add the necessary amount of distilled water to make the desired concentration of stock solution assigned to your group. [Note: Assume that the volume of the solute is negligible compared to the volume of the solution.] Concentration of STOCK SOLUTION, M Concentration of DILUTED SOLUTION, M 0.8 M 0.16 M 6. Make sure to place the computations used in the data sheet. PLEASE FILL IN THE MISSING TABLES IN THE DATA SHEET. THANK YOU!
