A 1.00 mol sample of neon is held at 298 K. The sample is slowly compressed until the external pressure reaches 400 atm. The ideal gas law predicts a volume of 0.061L under these conditions. Which of the following volumes is most reasonable for the real gas at 400 atm?
a) 0.061L
b) 0.055L
c) 0.070L
d) 0.066L
