(1) Consider 1 mol of an ideal gas at 300 K and 1 atm pressure. Imagine that the molecules are, for the most part, evenly spaced at the centers of identical cubes. Using Avogadro's constant and taking the diameter of a molecule to be 3 x 10-8 cm, find the length of an edge of such a cube and calculate the ratio of this length to the diameter of a molecule. The edge length is an estimate of the distance between molecules in the gas. (2) Now consider a mole of water having a volume of 18 cm³. Again, imagine the molecules to be evenly spaced at the centers of identical cubes and repeat the calculation in (a).
