If a sample of helium gas has a volume of 120 ml and a pressure of 850 mmHg, what is the new volume if the pressure is changed to 0.75 ATM at a constant T and n pls no links or downloads

Idon't see the pic?

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.

If this is a true or galse then its true but if not then what is the question?

Oxygen= 88ghydrogen= 12g
