What is the of a solution obtained by dissolving two extra-strength aspirin tablets, containing 594 of acetylsalicylic acid each, in 202 of water?

The active ingredient in aspirin is acetylsalicylic acid , a monoprotic acid with Ka=3.3*10^-4 at 25 C.

Can you provide the method, for some reason I keep getting the answer wrong.
