0.106 mg of stearic acid (M, = 284 g mol") is tound to cover s00 cm of water surface at the point where the surface pressure just' begins to rise sharply. Estimate the crOSS-sectional area, a, Der stearic acid molecule and thickness, t, of the surtace film or stearic acid on water. Given: density of stearic acid = 0.85 g cm
