To make a 5 mg per ml solution, start by determining the total volume of solution you need. If you need 100 ml, then you'll require 500 mg of your solute (as 5 mg x 100 ml = 500 mg). Dissolve the 500 mg of your solute in slightly less than 100 ml of solvent. Once fully dissolved, adjust the volume of the solution to exactly 100 ml with more solvent. Ensure accuracy by using a graduated cylinder or volumetric flask for measuring both the solute and solvent.

FAQs & Answers

  1. What does 5 mg per ml solution mean? A 5 mg per ml solution means that each milliliter of the solution contains 5 milligrams of the solute.
  2. How do you calculate the amount of solute for a specific volume? Multiply the desired concentration (mg/ml) by the total volume in milliliters to get the total amount of solute needed.
  3. What tools are best for measuring solutions accurately? Graduated cylinders and volumetric flasks are recommended for precise measurement of liquids and solutions.
