Sorry i dont understand the question can you rephase it?

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way. 

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
