The cell Pt|H2(1 bar)|HCl(m)|AgCl(s)|Ag
has an Stadard elctrode potential value of 0.2224V at 298K

Using the Nernst equation, calculate a value for the EMF when the HCl concentration is 0.20M.

I know what the Nernst equation is but I am unsure how to use it when I only have the concentration of one of the ions.
