The following cell was observed to have an emf of 2.25 volts at 25.0oC :
Zn(s) | Zn2+(aq, 0.143 M) || Cl2(g, 0.548 atm) | Cl-(aq, ?M) | Pt(s) .
Use tables of standard reduction potentials in Petrucci to calculate the concentration of chloride ion in the cathode compartment, [Cl-] / M . Your answer should be dimensionless (no units) and be given to 2
