a 2% weight by volume solution of aspirin has a molarity of 0.01. assuming 80% dissociation, calculate the pH?

i do not know where to start..i know to calculate pH its teh negative log of the concentration of hydrogen ions, but how do you work out the concentration of hydrogen ions from what is given?

Use your word: people do not know where to start to UNDERSTAND your question. The trouble is how a solution can be "2% weight by volume solution of aspirin has a molarity of 0.01". Do you simply mean that the solution of aspirin is 0.01 M, OR 2% by volume, Or 2% by weight?
Sorry you really need to let people first understand your question before people can try to help you.
