Now, for a complete equilibrium problem

Consider the following general reaction:

HC2H3O2 (aq)  + H2O (l) ⇌ H3O+ (aq)  + C2H3O2–(aq)   Kc = 1.8 x 10–5 (at 25 ºC)

If a solution initially contains (7.9x10^-1) M of HC2H3O2, (and no H3O+ or C2H3O2– ), what is the equilibrium concentration of H3O+ (aq) in the mixture?

In the appropriate blanks, provide the equilibrium [H3O+ (aq)], in the solution, in M, to two significant figures and to the appropriate power
