How is it that the atomic mass of an element can be converted to the mass of one mole? because the atomic mass in grams is equal to the mass of one mole, also in grams
because the atomic mass is exactly half the mass of one mole
because the atomic mass in amu is equal to the mass of one mole in grams
because the atomic mass is exactly 1.5 times greater than the mass of one mole

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
