The experiment is performed using a Petri dish 10.0 cm diameter, half-filled with water, and a solution of stearic acid in hexanes of concentration 0.140 g/L. The student calculated that the stearic acid molecule has a surface area of 0.210 nm^2.

Using the molecular formula of stearic acid and the accepted value of avogrado's number, calculate the volume of stearic acid solution (in uL) that the student added to form the monolayer.

Hint: make sure you have the correct number of significant figures, and that you correctly convert between nm^2 and cm^2, and that constant are not considered when deciding on your sig.fig.
