A company that produces footballs uses a proprietary mixture of ideal gases to inflate their footballs. If the temperature of 210210 grams [g] of gas mixture in a 15-liter [L] tank is maintained at 470470 degrees Rankine [°R] and the tank is pressurized to 125125 pound-force per square inch [psi], what is the molecular weight of the gas mixture in units of grams per mole [g/mol]?

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
