Question- A sample of octane in equilibrium with its vapor in a closed 1.0 L container has a vapor pressure of 50 torr at 45ÂºC. The container's volume is increased to 2.0 L at constant temperature and equilibrium is re-established. What is the vapor pressure?

1) The mass of octane is needed to calculate the vapor pressure

2) 50 torr

3) 25 torr

4) The external pressure is needed to calculate the vapor pressure

5) Greater than 50 torr

I need proficient help to solve the above problem
