Benzene is a known human carcinogen. The boiling point of benzene is 80. °C (reference 1).

a) Research online to find the short term exposure limit (STEL) for benzene. What does the STEL mean?

b) A friend is planning to do an experiment with liquid benzene at 21 °C on the open bench top in a small (18 m3 ) poorly ventilated room (i.e. consider the room to be a closed system for this question). Convert the STEL to vapour pressure for this room.

c) Calculate the theoretical vapour pressure of benzene inside the room at 21 °C. Use your data to explain to your friend why he can or cannot do the experiment.

d) Fully explain why the following equation (derived from the ideal gas law) cannot be used to calculate the vapour pressure/temperature data at another temperature/pressure. P1/T1 = P2/T2

Thanks!

Benzene and toluene form nearly ideal solutions. The boiling point of pure benzene is 80.1°C. Calculate the chemical potential of benzene relative to that of pure benzene when xbenzene = 0.30 at its boiling point. If the activity coefficient of benzene in this solution were actually 0.93 rather than 1.00, what would be its vapour pressure?

The molar enthalpy of benzene at its normal boiling point (80.09° C) is 30.72 kJ/mol. Assuming that Δ H of vaporization and Δ S of vaporization stay constant at their values at 80.09° C, calculate the value of ΔG of vaporization at 75.0° C, 80.09° C, and 85.0° C. Interpret these results physically.

1. A) The freezing point of benzene, C6H6, is 5.500 °C at 1 atmosphere. Kf(benzene) = 5.12 °C/m In a laboratory experiment, students synthesized a new compound and found that when 11.43 grams of the compound were dissolved in 267.0 grams of benzene, the solution began to freeze at 4.740 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound? ____g/mol B) The boiling point of benzene, C6H6,...
