Use the vapour pressures (at 0 °C) of the pure substances below to answer the following questions.

Substance P* (kPa)
cis-1-bromopropene (C3H5Br) 9.49
3-methyl-1-pentene (C6H12) 12





1. Determine the partial pressure (in kPa) of 3-methyl-1-pentene (C6H12) in the vapour phase (at 0 °C) over a solution for which the mole fraction of cis-1-bromopropene (C3H5Br) is 0.512. Report your answer to three significant figures in scientific notation.


Tries 0/3





2. A solution of cis-1-bromopropene (C3H5Br) and 3-methyl-1-pentene (C6H12) is prepared by adding 5.69 g of cis-1-bromopropene to 7.25 g of 3-methyl-1-pentene. Determine the mole fraction of cis-1-bromopropene in the vapor phase (at 0 °C). Report your answer to three significant figures in scientific notation.
