Answer:
The vapor pressure of ethanol in the solution is 10,27 kPa
Explanation:
To obtain the vapor pressure of a solution it is necessary to use Raoult's law:
<em>(1)</em>
The moles of ethanol are:
18,00mL×
×
= 0,3083 mol Ethanol.
Moles of benzoic acid:
12,55 g×
= 0,1028 mol benzoic acid.
Thus, mole fraction of solvent, X, is:
=<em> 0,7499</em>
Replacing this value in (1):
= <em>10,27 kPa</em>
<em></em>
