If 1000 L of gasoline has spilled into the street (MW=117 g/mol, density=0.7 g/mL which is true for octane) then firefighters add a lot of a material that dissolves into it that reduces the vapor pressure (liquid octane doesn’t burn, only the vapors). The firefighters put 500 kg of a material into the gasoline and reduced its vapor pressure from the pure partial pressure of 10.0 kPa down to 8.0 kPa. What is the molecular weight of the material that was added? (hint: use Raoult’s Law, which relates changes in pressure to the mol fractions.
