The mole fraction of the non-volatile solute in the solution is 0.13.
<h3>Mole fraction of solute </h3>
Using law of vapor pressure formula
Mole fraction of the non-volatile solute=Vapor pressure of the pure acetone-Vapor pressure of the solution /Vapor pressure of the pure acetone
Where:
Vapor pressure of the pure solvent (acetone) =266 torr
Vapor pressure of the solution =232torr
Mole fraction of solute = ?
Let plug in the formula
Mole fraction of the non-volatile solute=266-232/266
Mole fraction of the non-volatile solute=34/266
Mole fraction of the non-volatile solute=0.127
Mole fraction of the non-volatile solute=0.13 (Approximately)
Inconclusion the mole fraction of the non-volatile solute in the solution is 0.13.

An example of a problem with the introduction of new goods in the construction of the CPI is: the invention of cell phones.
<h3>What is CPI?</h3>
CPI is an acronym for consumer price index and it can be defined as a measure of the the average change in prices for a weighted average basket of goods and services that are purchased by households in an economy, over a specific period of time.
This ultimately implies that, a consumer price index (CPI) can be used to estimate the price changes in a weighted average basket of goods and services that are purchased by households in an economy, over a specific period of time.
In conclusion, an example of a problem with the introduction of new goods in the construction of the consumer price index (CPI) is the invention of cell phones.
