What's the pH of 0.15M C3H6O3?

To determine the pH of a solution, we need to know the concentration of the hydrogen ions (H+). The compound C3H6O3 is more commonly known as glycerol, which is a triol.

However, glycerol is not an acid and does not directly contribute hydrogen ions to the solution. Thus, its concentration does not directly affect the pH.

If you meant to ask about a different compound that is an acid, please provide the correct chemical formula, and I can assist you in calculating its pH.
