What is the molarity of OH- in a 5.78×10-3 M C6H5CO2Na solution that hydrolyzes according to the equation.

C6H5CO2-(aq) + H2O(l) = OH-(aq) + C6H5CO2H(aq)

• General Chemistry -

Kb = (Kw/Ka) = (OH^-)(C6H5COOH)/(C6H5COO^-)
Plug in values for Kw, Ka, x for OH and x for C6H5COOH, and 5.78E-3 for C6H5COO^-) and solve for x.
