Answer:

Explanation:
= Initial pressure = 200 kPa
= Final pressure
= Initial temperature = 
= Final temperature = 
We have the relation

The pressure that would be exerted after the temperature change is
.
Answer:
The boiling point is somewhere between 56 and 151 °C
Explanation:
Hello,
In this case, it is possible to compute it via rigorous methods in phase equilibrium by using for example a cubic equation of state to model the vapor phase and a suitable excess Gibbs free energy model for the liquid phase, nonetheless, it is an arduous task. In such a way, since the information about both acetone's and nonane's pure boiling points is given as well as acetone's mole fraction, which points out it is about a binary liquid solution, one could make up the boiling point is somewhere between 56 and 151 °C precising that it should be closer to 151 °C as the mixture is 90% nonane and 10% acetone.
Best regards.
