Part 1. A chemist reacted 12.0 liters of F2 gas with NaCl in the laboratory to form Oz gas and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with Fz at 280. K and 1.50 atm. F2 + 2NaCl - Cl + 2NaF
Part 2. Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
