Answer:
Vapour pressure of a liquid varies with temperature
Explanation:
The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.
Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.

Hello!</h2>
The answer is: Charle's Law.
<h2>
Why?</h2>
The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.
The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:
![\frac{V}{T}=k](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BT%7D%3Dk)
Where,
![V=Volume\\T=Temperature\\k=constant](https://tex.z-dn.net/?f=V%3DVolume%5C%5CT%3DTemperature%5C%5Ck%3Dconstant)
Also, to describe the relationship between two differents volumes at different temperatures, we have:
![\frac{V_{i}}{T_{i}}=\frac{V_{f}}{T_{f}}](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7Bi%7D%7D%7BT_%7Bi%7D%7D%3D%5Cfrac%7BV_%7Bf%7D%7D%7BT_%7Bf%7D%7D)
Where,
![V_{i}=InitialVolume\\T_{i}=InitialTemperature\\V_{f}=FinalVolume\\T_{f}=FinalTemperature](https://tex.z-dn.net/?f=V_%7Bi%7D%3DInitialVolume%5C%5CT_%7Bi%7D%3DInitialTemperature%5C%5CV_%7Bf%7D%3DFinalVolume%5C%5CT_%7Bf%7D%3DFinalTemperature)
Have a nice day!

Assuming that your 2.0 m is an M for molarity
I used the formula M=number of mold/L
Converted 250mL to .250L by dividing by 1000
