An oleic acid, C17H33COOH (282g/mol), solution is added to water in a watchglass until a monolayer forms. Assume that there are no spaces between molecules in the monolayer and that each oleic acid molecule occupies an area of 0.25nm^2. If the concentration of the oleic acid solution is 0.00012g/ml, what is the experimental value of avogrados number?
dropper piper calibration =65 drops/ml
number of drops of oleic acid in the monolayer = 16
drops diameter of monolayer= 14.5cm
