A Sample Of Oxygen Gas Occuples A Volume Of 250.Ml At 740.Torr Pressure.What Volume Will It Occupy At 800.Torr Pressure

A sample of oxygen gas occuples a volume of 250.ml at 740.torr pressure.what volume will it occupy at 800.torr pressure

 

Answer: 231.25 ml

We can assume that it is ideal or perfect gas and we can use the formula from Boyles law relating the pressure and volume of the gas.

Given: initial pressure (P1)= 740 torr

           Initial volume (V1)= 250 ml

           Final pressure (P2)= 800 torr

Required: Final Volume (V2)

Solution:

(P1)(V1)=(P2)(V2)

V2 =

V2 =

V2= 231.25 ml

We can see that as the pressure increases, the volume will decrease. Therefore, the pressure and volume of an ideal gas (at constant temperature (isothermal) and constant number of moles ) is inversely proportional.
