Ametallurgist reacts 320.0 grams of 75.0% by mass silver nitrate solution with an excess of copper metal. how many grams of silver metal can the metallurgist produce during the process?

cu(s) + agno3 → ag(s) + cu(no3)2

97.5 grams
125 grams
149 grams
152 grams

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
