Answer:
Mole fraction of water(H₂O) is 0.5 and the mole fraction of CH₃OH(Methanol) is 0.5.
Explanation:
Greetings !
The molecular weight of CH₃OH(Methanol)=32g/mol
The number of moles of CH₃OH=
=4moles
The molecular weight of water H₂O =18g/mol
The number of moles of=
=4moles
Total number of moles in the solution =4mol + 4mol
=8mol
Mole fraction Methanol CH₃OH=
=0.5mol
Hope it helps!

Hank's Garage has an air compressor with a holding tank that contains 200L of compressed air at 5200 torr. One day a hose ruptured and all the compressed air was released to a volume of 1370 L at atmospheric pressure.
Hank's Garage has an air compressor with a holding tank that contains a volume of 200L (V₁) of compressed air at a pressure of 5200 torr (P₁).
One day a hose ruptured and all the compressed air was released. The final pressure was the atmospheric pressure (1 atm = 760 torr) (P₂).
We can calculate the new volume (V₂) in these conditions using Boyle's law, which states there is an inverse relationship between the volume and the pressure of an ideal gas.
