The concentration of the hydronium ions is $1.41 \cdot {10}^{- 6} \text{M}$.

#### Explanation:

To get from pH to the concentration of hydronium ions, ${H}_{3} {O}^{+}$, which can be written as thecocnentration of ${H}^{+}$ ions, all you need to do is use

$\left[{H}_{3} {O}^{+}\right] = {10}^{- p {H}_{\text{sol}}}$

IN your case, a pH of 5.85 would correspond to a concentration of ${H}_{3} {O}^{+}$ ions equal to

[H_3O^(+)] = 10^(-5.85) = "0.00000141 M" = color(green)(1.41 * 10^(-6)"M")#
