Question

I have a solution that contains 3 inactive ingredients: ethanol, propylene glycol, purified water and 5% of an active ingredient. What would be the smartest way to figure out the concentrations of the 3 inactive ingredients? Ideally something I can do at home without spending too much money.

Answer 1

To figure out the concentrations of the three inactive ingredients in your solution, you can use the concept of volume percentage.

This involves measuring the volume of each inactive ingredient and the total volume of the solution to calculate their concentrations.

Step-by-step explanation:

To figure out the concentrations of the three inactive ingredients in your solution, you can use the concept of volume percentage.

Volume percentage is the volume of solute divided by the volume of the solution, multiplied by 100%.

In your case, you can measure the volume of each inactive ingredient and the total volume of the solution to calculate their concentrations.

For example, if you have 100 mL of the solution and 20 mL of ethanol, the concentration of ethanol would be (20 mL / 100 mL) * 100% = 20%.

Using this method, you can determine the concentrations of ethanol, propylene glycol, and purified water in your solution.
