Explain in detail how you would find the density of an unknown high-density object if you had only the objects listed below.If you show calculations, make sure you define your variables.Assume all containers are large enough to hold the object....

You have:

1. - A spring scale (the hanging kind, not a bathroom scale)
- an unmarked bucket containing a liquid of known density (not water)

weigh the object
weight the object while it is submerged.

From those two things, you can determine the mass, and the volume.
weight in water = WW Newtons
weight in air = WA Newtons

mass = WA/9.81 kilograms

(if your scale reads in kilograms, multiply by 9.81 m/s^2 on earth to get Newtons)

difference = WA-WW = buoyant force = volume*density of water * 9.81

density of water = 1,000 kg/m^3
so
difference = 1000*V * 9.81
=9810 V Newtons
so
9810 V = WA-WW
V = (WA-WW)/9810

Mass of object/Volume of object
= density
= [WA/9.81] /[(WA-WW)/9810] kg/m^3

= [WA/(WA-WW) ]1000 kg/m^3
