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.
