At room temperature in equilibrium, $[$H$+]=[$OH$-]61013$ cm$-3$ in water. The

diffusivites of the H$+$ and OH$-$ ions are $9\mathrm{.}310-5$ cm$2$ sec$-1$ and $5\mathrm{.}310-5$ cm$2$ sec$-1,$

respectively. Using the Nerst$-$Einstein relationship $=$ zqD$/$kT$,$ where $$ is mobility, z

is the charge on the ion and D is diffusivity $($kT$/$q is known to you$),$ calculate the ion

mobilities, and the DI water resistivity
