The acid dissociation constant, Ka, for this reaction is given by the following formula (this is also in your book):
Ka=[H3O+][A−][HA]
The acid concentration, [HA] is given in the introductory information of this problem. Using this information and your answers from the previous two questions, calculate Ka for this acid.

I suggest you read these things before you post them. You provided absolutely no information other than it is in the introductory information. But I don't see any introductory information.
