Identification of an Unknown Organic Acid?

Titrated using computers/ pH probes.Have all graphs, data, equivalence points, all the data. How can we figure out which acid it is if we were given a list of organic acids and their molar mes. I know we will have to do some form of stoichiometry to find the molar m (g/mol) of the unknown acid. once we have that number we can find the acid. What calculations do we need to do to find that number?
