Concentration of H+ using voltage and M
« on: April 13, 2005, 04:39:03 PM »
If the voltage of a Zn- H+ cell is 0.67V where the [Zn^+2]=1.25M and the PH2=1atm, what is the concentration of H+?

I've tried 0.67V=-0763 -(0.0257/2)ln[(H+)^2/(1.25M)(1.0atm)]

I can't get the ln part, where to solve for H+ with an exponent

ln (A/B) = ln A - ln B
