Question

Can you help me determine 

  • the required amount of 500mg ascorbic acid tablets to puverize 
  • the necessary amount of distilled water to make the desired concentration of stock solution (0.1M)

Show complete and justifiable computations pls. 

4. Mix and stir the powder with the distilled water until homogeneous. 5. Label the bottle properly. Make sure to label this as your stock solution and indicate its concentration, total volume of solution, and chemical name. Note: Check the MSDS for the ideal storage conditions for ascorbic acid- containing solutions. Adjust and modify according to its sensitivity. 6. Document using a photo with a white / plain background. 7. Compute and add more solvent to achieve the desired dilution. Use the prepared stock solution to prepare an aliquot assigned to your group. Make sure to place the computations used for dilution (C1V1 = C2V2) in the data sheet. 8. After dilution, label the aliquot with its concentration and total volume of solution, and document using a photo with white / plain background. 9. Complete the data sheet and place hand-written notes on the relevant solutions in solving for the amounts needed in the experiment.

Experiment #1 – Preparation of Ascorbic Acid Stock Solution and Dilution Materials: 500 mg ascorbic acid tablets 2L Distilled water Measuring cups / measuring spoon Mortar and pestle Stirrer Parchment paper or any non-porous sheet Dropper or syringe with no needle (optional) Weighing scale (optional) Amber bottle; or Glass bottle with tint; or Glass bottle and aluminum foil Masking tape; or Sticker label Permanent marker Methods: 1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat sheet. 2. Pulverize the required amount of 500 mg ascorbic acid tablet/(s) into fine powder. Note: Assume that the tablet contains pure 500 mg ascorbic acid without any excipient/(s). The amount of tablets will depend on the concentration assigned to your group. 3. On a clean and dry glass bottle or tinted jar, add the necessary amount of distilled water to make the desired concentration of stock solution assigned to your group. Make sure to place the computations used in the data sheet. STOCK SOLUTION DILUTE TO: GRP 1 0.1 M solution 0.02 M solution
