    Hey there. I am having trouble with this question.

    Phenylacetic acid (C6H5CH2COOH) is one of the substances that accumulates in the blood of people with phenylketonuria, and inherited disorder that can cause mental retardation or even death. A 0.085 M (mol/L) solution of C6H5CH2COOH has a pH of 2.68. Calculate the Ka value for this acid.

    Could you please show the work. And no power points please.

    Thanks in advance!
