13.0 moles of gas are in a 8.00 L tank at 21.0 ∘C . Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol. Express your answer with the appropriate units.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )
