1. Glacial acetic acid, the most concentrated CH3COOH you can buy, has a concentration of 17.54 M. Calculate the concentration of CH3COOH in a solution that is prepared by combining 15.0 mL of glacial acetic acid with enough water to make 250-mL of solution. 2. Calculate the pH of the glacial acetic acid and the solution your prepared in step 1. 3. An unknown acid is prepared by diluting 0.19 moles in enough water to make a 1.0L solution. This solution of unknown acid was found to have a pH of 2.74, calculate the ka of this mystery acid.
