In 1765, Benjamin Franklin described experiments that he had done on Clapham Pond near London. He observed that a teaspoon of oil (2.5 cm³) placed on the water surface would calm the surface up to 2000 m². Assuming the oil was oleic acid (below, left image) with a molar mass of 282 g/mol and a density of 0.895 g/cm³, calculate the thickness of the monolayer (nm) and the area per molecule (a^o, nm²/molecule). Based on a^o and the

A isotherm for oleic acid (below, right image), what phase is the oleic acid monolayer at pond's air-water interface?
