Question - Enough of a monoprotic acid is dissolved in water to produce a 0.0190 M solution. The pH of the resulting solution is 6.39.

Calculate the Ka for the acid. The answer is not 8.734*10^-12. The hint says something about using the the orginal H+ value 10^-7 of the water.

Depict your all computation in detail so I can recognize the solution methodically
