Prоf. Hаmiltоn is running аn experiment with аn оld-fashioned liquid helium dilution refridgerator. A "cold trap" is set up to cause molecules to linger near the suction in the fridge's vacuum system, to keep impurities from circulating with the liquid helium. If the cold trap has an effective volume of 0.200 L and is maintained at 13.0K, how many molecules are in it at 10.0 Pa of pressure? (Avogadro's number is 6.022 × 1023 molecules/mol, and the universal gas constant is 8.314 J/mol ∙ K. Assume the behavior of an ideal gas.)
