A chemist dissolves 119, mg of pure nitric acid in enough water to make up 140 . mL of solution. Caiculate the pH of the solution. Round your answer to 3 significant decimal places.
The pH of a 0.53M solution of carbonic acid (H2CO3) is measured to be 3.31. Calculate the acid dissociation constant Ka of carbonic acid. Round yorur answer to 2 significant digits.
