6.At a pressure of 5.0 atmospheres, a sample of gas occupies 40 liters. What volume will the same sample occupy at 1.0 atmosphere?
(a) 50 L
(b) 100 L
O (C) 80 L
(d) 200 L

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
