But the units are no longer moles/L, but rather millimoles/L or mmol/L. These units are called millimolar or mM. While in many cases scientists prefer to talk about concentration in terms of molarity, it can sometimes be more useful to talk about mass per liter solvent. For example, ...
Now that we have identified the standard cell potential and the number of moles of electrons transferred, we just need to plug them into the Nernst equation. 3.80V=0.0592V2⋅logK Step 3:Rearrange the equation algebraically to solve for the equilibrium constantK. ...
