To effectively stop polymerization, certain inhibitors require the presence of a small amount of O2. At equilibrium with 1 atm of air, the concentration of O₂ dissolved in the monomer acrylic acid (CH₂=CHCOOH) is 1.64x10⁻³ M.(b) If 0.005 atm of O₂ is sufficient to stop polymerization, what is the molarity of O₂?
