Question

In Benjamin Franklin's oil drop experiment, 5 cc of oil was spread on a lake covering about 2000 sq. meters. Assuming that the oil forms a mono-molecular layer, estimate the area occupied by a single oil molecule in sq angstroms. Assume the density of the oil to be 0.9 gms/cc and the molecular weight to be 300 grams/mole. Show calculation steps.
