Consider 1 mol an ideal gas at 28°Cand 1.05atmpressure. To get some idea how close these molecules are to each other, on the average, imagine them to be uniformly spaced, with each molecule at the center of a small cube.
Part A
What is the length of an edge of each cube if adjacent cubes touch but do not overlap?
l = 3.39×10-9m
Part B
How does this distance compare with the diameter of a typical molecule? The diameter of a typical molecule is about 10-10m.
Express your answer using one significant figure.
Part C
How does their separation compare with the spacing of atoms in solids, which typically are about 0.3 nm apart?
