Density Determination Lab Report Example Essay Example

INTRODUCTION:

The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density.

PROCEDURE:

1. Obtain a solid metal
2. Weigh the dry sample carefully to the nearest 0. 0001 grams on the top loading balance.
3. Determine the volume of your unknown solid sample by liquid displacement.
4. Select a graduated cylinder (for best volume determination smaller is better) into which the solid can be inserted.
5. Fill your cylinder about half full of water and record the temperature.
6. Then read the volume as precisely as possible and record it
7. Tilt the
   ...

   cylinder and slide the solid down the inside being careful not to splash water out of the cylinder.

8. Record the volume.
9. The increase in the volume of water in the cylinder gives the volume of the solid.
10. Determine the density of the solid by using this equation: Density = Mass/ Volume
