Use the vapour pressures (at 0 °C) of the pure substances below
to answer the following questions.
| Substance | P* (kPa) | |
| trans-2-hexene (C6H12) | 6.2 | |
| tetrachloromethane (CCl4) | 4.49 |
1. Determine the partial pressure (in kPa) of tetrachloromethane
(CCl4) in the vapour phase (at 0 °C) over a solution for
which the mole fraction of trans-2-hexene
(C6H12) is 0.930. Report your answer to three
significant figures in scientific notation.
| Tries 0/3 |
2. A solution of trans-2-hexene (C6H12) and
tetrachloromethane (CCl4) is prepared by adding 7.89 g
of trans-2-hexene to 7.73 g of tetrachloromethane. Determine the
mole fraction of trans-2-hexene in the vapor phase (at 0 °C).
Report your answer to three significant figures in scientific
notation.
