See the answer below.

Work Step by Step

Number of moles of water vapor: $375\ g\div 39.948\ g/mol=10.42\ mol$ Van der Waals equation: $\left[P+a\left(\dfrac nV\right)^2\right](V-bn)=nRT$ $(P+5.82\ atm)×4.66\ L=254.83\ L.atm$ $P=48.8\ atm$ Ideal gas: $PV=nRT$ $P=50.96\ atm$ The term $bn$ has a slightly bigger influence in this difference.
