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
RESULTS:
| TEMPERATURE BEFORE| TEMPERATURE AFTER| VOLUME BEFORE| VOLUME AFTER| VOLUME OF SOLID| 1| 24| 23| 63| 70| 7|
2| 24| 23| 74.2| 81.1| 6.9|
3| 24| 24| 78| 84.5| 6.5|

Experiment 1: Determination of Density
Introduction
The purpose of this experiment was to be able to measure the density of water and an unknown substance with a buret and an analytical balance. The density can be calculated by dividing the mass per volume. It was expressed in grams per cubic centimeters, or in this case, grams per milliliters....

...Experiment: determination of densities
Introduction
The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples, a unit volume means 1.0 ml. The units of density, therefore, are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter.
Density is often used as a point of...

...INTRODUCTION
1.1 Background of the Experiment
Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids, density is represented by the ratio of its mass and volume. It is given by the equation
ρ= massvolume 1.
The SI unit of density is kg/m3. However, its CGS units, g/cm3 or...
