A chemist wishes to prepare 148.00 mL of acetic acid/sodium acetate buffer solution with a pH of 5.29 and a total concentration of the components equal to 0.47 M. The pKa for acetic acid is 4.75. What mass of acetic acid (molar mass 60.05 g/mol) is required?
What mass of sodium acetate (molar mass 82.03 g/mol) is required?

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
