A teaspoon of an organic oil dropped on the surface of a quiet pond spreads out to cover almost an acre. The oil film has a thickness equal to the size of a molecule. In the lab, when you drop 0.001 milliliter(10-9 m3) of the organic oil on the still surface of water, you find that it spreads to cover an area of 1.0 m2. If the layer is one molecule thick, what is the size of a single molecule?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
