The compound CH3F has van der Waals constants a = 5.009 atm•L2

Question

/mol
2
and b = 0.0562 L/mol.
Using both the ideal gas law and van der Waals’s equation, calculate the pressure expected for 25 mol of
CH3F gas in a 5.00-L container at 75 °C.

no idea how to even start this one...

Answer 1

Of course you do. Look in your text, find the van der waals equation, substitute the numbers and solve for P.

Then in a separate calculate, use PV = nRT and calculate P.
Post your work if you get stuck. This just some algebra to go through.
