a spherical object with a mass of 2g was shown to sink to the ottom of a beaker containing ethanol and float on the surface of water at 25 degrees C. Using this inrmation, calculate an acceptable range of balues for the diameter of the sphere. (at 25 degrees C the density of ethenol is .79 g/ml and the density of water is 1g/m: the volume of a sphere may be expressed as V=4/3pi r squared.

Well, you need to start by thinking about what the question is getting at. What do you think the path to the answer is? Do you understand the conditions for buoyancy? Can you explain where you are having problems?
