Question

With the use of Archimedes principle, state how you will find relative density of a solid denser than water and insoluble in it. How will you modify your experiment if the solid is soluble in water?

Answer 1

Archimedes' principle states that the upward buoyant force, which acts perpendicularly in the upward direction, exerted on a body immersed in a liquid, whether partially or wholly submerged, is equal to the weight of the displaced fluid.Density= Weight/VolumeIf a solid is denser than a given fluid, the solid will sink in the said fluid. And as stated above, by sinking the solid displaces the fluid volume equivalent to its weight (it displaces its weight in the fluid)To calculate the density of the insoluble solid denser than water;•    Weigh the solid•    Put it in water in a graduated cylinder. The volume of the displaced water is the volume of the solid.  •    Since you now have both the weight and the volume of the solid, use the formula to calculate its density.If the solid is soluble in water, replace water with other liquid in which the solid is insoluble.
