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.
