Can you help with this one please?
A drop of oil (vol 0.05cm^3) is released on to a calm surface of a pond where it spreads out and covers an area of 40 cm^2. Assume the oil film has uniform thickness equal to the diameter of an oil molecule. Calculate the diameter of an oil molecule and express your answer in scientific notation to an appropriate # of sig. fig.
please see the post I got from bob
