What are dilution ratios and how do I calculate them?

Dilution ratios represent the proportion of a substance in a solution. To calculate it, divide the volume of the solute by the total volume of the solution.

Can you give me an example of how to calculate a dilution ratio?

Sure! If you have 10 mL of a solution and you add 90 mL of water, the dilution ratio is 10 mL (solute) to 100 mL (total solution), or 1:10.

What if I want to make a 1:5 dilution from a stock solution?

To make a 1:5 dilution, mix 1 part of the stock solution with 4 parts of the diluent. For example, 20 mL of stock with 80 mL of water.

Are there any common mistakes to avoid when calculating dilution ratios?

Yes, common mistakes include miscalculating the total volume or not accounting for the volume of the solute when adding diluents.
