I have a problem that I need help with. The diameter of the oil molecule has to be calculated and presented in scientific notation. The data in the questions tells me that drop of oil(volume 0.05cm ^3) is released from a dropper onto the surface of the water.The film of oil has the thickness of the diameter of an oil molecule.
The volume of the oil is thickness* area of film.
set that equal to the volume of the drop, given, and solve for thickness.
thank you Bob, I will try this and see how I get on.
