What is the volume of 0.40 grams of O2 gas at Standard Temperature and Pressure (STP)? Standard Temperature and Pressure (STP) = 273 K and 1.0 atm
Convert grams to moles by dividing by molar mass of O2

A: 0.295 liters
B: 0.28 liters
C: 0.25 liters
D: 0.235 liters

What’s the question

Ibelieve y y even though i've only taken chemistry for one year

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.

The answer is d. hope i !
