Answer:

The concentration of the hydronium ions is #1.41 * 10^(-6)"M"#.

Explanation:

To get from pH to the concentration of hydronium ions, #H_3O^(+)#, which can be written as thecocnentration of #H^(+)# ions, all you need to do is use

#[H_3O^(+)] = 10^(-pH_"sol")#

IN your case, a pH of 5.85 would correspond to a concentration of #H_3O^(+)# ions equal to

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