We're also given the concentrations of nickel of this guy and the concentration of the zinc in the acreage state of this guy. So notice that two and three represent nonstandard conditions. And in fact, our goal is to find the cell potential under these nonstandard state conditions. So whenever we hear the word nonstandard and cell potential, we have to think nurse equation. That's exactly what we do in step two. But before we can use this equation, we have to find our Q.
