Calculation of density of various metals

 

Background:
Density is the mass of an object per unit of volume. In other words metals with the same mass will occupy less or more space depending on their density.A metal with a high density will occupy a smaller space than a metal with a low density.A metal with a low density will occupy a larger space than a metal with a higher density.This space the metals occupy is called volume.


Mass- The amount of matter in an object.

Volume- The space an object takes up.
Density- Mass divided by volume. M=D/V

How to calculate the density of a metal:

Since density is mass per unit volume,the density of a metal can be calculated by submerging it in a known amount of water and measuring how much the water rises.This rise is the volume of the metal. Its mass can be measured using a scale. The unit for density is gm/cm3.

Materials:
Different metals cylinders of the same mass if possible.
Scales for calculating mass.
Graduated cylinders large enough to immerse the metals completely.

Procedure:
1. Weigh each metal cylinder and record in a data table.
2. Fill the graduated cylinder to a set mark and record that level in your data table.
3. Carefully put one of the cylinders into the graduated cylinder and record the new level in the data table.
4. Repeat with the other metal cylinders.
5. Put all the equipment that was gathered back to its original place.

Results:
Calculate the density of all the cylinders. The volume is the difference between the original water level, and the
new water level.

Conclusions:
1. Which metal had the highest density?
2. What conclusions can you make about mass, volume, and density?
