The voltage generated by the zinc concentration cell described by,

Zn(s)|Zn2+ (aq, 0.100 M)||Zn2+ (aq, ____ M)|Zn(s)
is 24.0 mV at 25 °C. Calculate the concentration of the Zn2 (aq) ion at the cathode.

My textbook advised me to use the Nernst Equation and by rearranging and substituting i got x=0.0444498 M.. Can somebody please tell me if that is that correct?

I don't get that. I think (Zn^2+) is greater than 0.1 M, not less.
