A concentration cell was set up at $327K$ using two hydrogen electrodes. If the cell is generating a potential

of $0\mathrm{.}0270V,$ answer the following question:

What is the concentration of $H^{+}$in the cathode's half$-$cell solution, if the anode's half$-$cell is $1M?$

$[H^{+}{]}_{\text{c}\text{a}\text{t}}=$

number $($ rtol$=0\mathrm{.}03,$ atol$=1$e$-08)$
