In water conservation, chemists spread a thin film of certain inert material over the surface of water to…?

cut down the evaporation rate in reservoirs. This technique was pioneered by Benjamin Franklin three centuries ago. A volume of 0.10 mL of oil could spread over a surface area of 40.25 m^ 2. Assuming that the oil forms a monolayer; that is, a layer of one molecule thick, estimate the length of each oil molecule in nanometers ( 1nm=1×10^-9m)

Please provide steps

From the volume of oil added, you can calculate the thickness since you are given the surface area.
T = V / SA
First convert the volume into cubic meters and then you shouldn’t have any problems.
