To obtain the density you need to know the mass, and the volume of the object.
So you'd have to weigh it using a balance to obtain the mass.
The easiest way to measure the volume (particularly if it's an irregular shape) would be via the displacement of water.
density = mass / volume
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
The density is the ratio of mass to volume. It doesn't matter what size the piece of metal, if it is the same metal it has the same density, 8.4.
it isnt! a rectal is.
It's simple really. The steel ship floats because it is filled with air compartments which allow it to be less dense than the water. The steel piece does not have any air pockets/compartments meaning it is denser than water thus the steel piece sinks.Big ship not metal all the way through. If you think of all of ship, it is mostly air with metal frame and skin of metal around it, so its average weight (density of entire thing times volume) much less than solid metal. If average weight less than weight of water of same size, then water heavier than it, water pushes it up, and it floats.First of all, an object floats if its OVERALL density is less than the density of the fluid in which it is placed.(it can be shown)The metal ship, due to the large pockets of air inside the ship, has a lower density than water.The piece of metal has a higher density than water.Thus, the piece of metal sinks while the metal ship floats.A cruise ship has a lower density than compared to a coin as mass divided volume = density thus a lower density will allow the object to float.Buoyant force says that the force an object is buoyed up with is equal to the weight of the water the object displaces. A cruise ship is large and displaces a lot of water so it is buoyed up with a large force. A coin is small and displaces very little water and therefore the buoyant force is very little.
The same.
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
That would vary greatly depending on the type and density of the metal, along with the dimensions of the particular piece. The weight of a piece of anything is the volume times the density.
The density is the ratio of mass to volume. It doesn't matter what size the piece of metal, if it is the same metal it has the same density, 8.4.

100mL of measuring cylinder is the most appropriate (more than beaker) piece of equipment to measure 85mL of water.
-- Get a piece of the material. It doesn't matter what size it is. -- Measure the mass of the sample. -- Measure the volume of the sample. -- Divide the mass by the volume. The result is the density of the material.

A dynamometer or "dyno".
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
