1) A material will float on the surface of a liquid if the material has a density of less than that of the liquid. Given density of water as 1.0g/mL, will a block having a volume of 1.2*10^4 in^3 and weighing 350 lb float or sink?
2) The density of pure silver is 10.5g/cm^3 at 20 degrees C. If 5.25 grams of pure silver pellets is added to a graduated cylinder containing 11.2 mL of water, to what volume will the water in the cylinder rise?© BrainMass Inc. brainmass.com October 24, 2018, 5:53 pm ad1c9bdddf

The solution provides a step by step process to solve the two problems.
Application of Archimedes' Principle and Law of Flotation
A balloon filled with Helium and air is designed to support a mass of 106kg (payload+ empty balloon) and the mass of gases which fill it.Air density is 1.29kg/m^3, Helium plus air density in the balloon is 0.247kg/m^3, and Helium density is 0.179kg/m^3. Ignoring the volume of the payload, find the volume of the balloon. Answer in units of m^3.View Full Posting Details
