On tungsten surface a saturated single monolayer of CO absorbed has a mass per unit area of 4.65e-8 g/cm^2. Suppose that the width of the CO molecule is diameter of a circle inscribed in a square, and the CO is absorbed via C-atom and stands up on a tungsten surface.
1. Determine the numbers of CO molecules are absorbed on the surface per square centimeter.
2. Calculate the "effective area" of a single CO molecule.
3. Calculate the effective diameter of one absorbed CO molecule?
Calculate the actual area covered by a single CO molecule on the tungsten surface if you use the width of the CO molecule as the diameter of a CO molecule.
