At room temperature (20 °C) and pressure, the density of air is1.189 g/L. An object will float in air if its density is less than thatof air. In a buoyancy experiment with a new plastic, a chemistcreates a rigid, thin-walled ball that weighs 0.12 g and has a vol-ume of 560 cm³.(a) Will the ball float if it is evacuated?(b) Will it float if filled with carbon dioxide (d=1.830 g/L)?(c) Will it float if filled with hydrogen (d=0.0899 g/L)?(d) Will it float if filled with oxygen (d=1.330 g/L)?(e) Will it float if filled with nitrogen (d=1.165 g/L)?(f) For any case that will float, how much weight must be addedto make the ball sink?

You are assigned the task of separating a desired granular materialwith a density of 3.62 g/cm3 from an undesired granularmaterial that has a density of 2.04 g/cm3. You want to dothis by shaking the mixture in a liquid in which the heaviermaterial will fall to the bottom and the lighter material willfloat. A solid will float on any liquid that is more dense.
