Introduction:

Density is a measure of the mass per unit volume of a substance. It is an important physical property that can be used to identify and classify materials. In this lab, we will be determining the densities of various materials by measuring their masses and volumes.

Methods:

To begin the lab, we gathered a variety of materials such as metal cylinders, wooden blocks, and plastic cubes. We also obtained a balance and a graduated cylinder.

First, we determined the mass of each material using the balance. We placed the material on the balance and recorded the mass to the nearest 0.01 grams.

Next, we determined the volume of each material using the graduated cylinder. For the metal cylinders and wooden blocks, we measured their volumes by immersing them in water and recording the change in water level. For the plastic cubes, we measured their volumes by using a ruler to measure their length, width, and height, and then calculating the volume using the formula V = l x w x h.

Once we had both the mass and volume measurements for each material, we were able to calculate the density using the formula D = m/v, where D is the density, m is the mass, and v is the volume.

Results:

The results of our density measurements are shown in the table below:

MaterialMass (g)Volume (mL)Density (g/mL)
Metal cylinder 125.3518.001.41
Metal cylinder 237.4225.501.47
Wooden block 120.6815.501.33
Wooden block 232.9324.501.35
Plastic cube 115.2912.001.27
Plastic cube 222.4218.001.24

Discussion:

Overall, our density measurements were consistent with the known densities of these materials. The metal cylinders and wooden blocks had densities within the expected range for these materials, and the plastic cubes had densities that were slightly lower than expected.

One potential source of error in our measurements was the possibility of air bubbles trapped within the materials, which could have affected the volume measurements. Additionally, the accuracy of our mass measurements may have been affected by the precision of the balance.

Conclusion:

In conclusion, we were successful in determining the densities of various materials using the methods described. These density measurements can be used to identify and classify materials based on their physical properties.

## Density Determinations Lab, Lab Report Example

Lowe giving his take on mental causation by Non-Cartesian substance Dualism. We then placed a sample of Lead in the graduated cylinder. The hypothesis of this lab was that density of the marble does not depend on mass, volume but only depends on the type of materials that the marble is made of. . On the other hand, If we had taken 30 ml water instead of 20 ml of water.

The precipitate was then transferred into the filter paper with a stream of water of the wash bottle. The graduated cylinder was then tilted; this was followed by carefully dropping the marble in to the cylinder and then measuring the total volume of water mL. . Ten post-1985 pennies were immersed into the cylinder, in pairs, and the new volumes and masses recorded. .

. The system of capitalism heavily. Hold the dropper pipette vertically while counting the drops into a 10 mL graduated cylinder. Once that was done, the flask was cleaned with an unknown solution provided by the instructor and then the flask was filled with the same unknown solution up to the mark. Archimedes' approach is one of the applicable techniques for determining density of a substance. We then just repeat this procedures for solutions B and C making sure to rinse and dry both sinker and beaker before weighing. Temperature is a vital factor that could affect the results of the experiment.

For instance, by means of magnetic resonance imaging researchers have noted the differences in the volume and density of various brain zones between the healthy individuals and patients with BD. We would then have to pour the water out into a small beaker and dump the penny out refill the graduated cylinder and add any lost amount of water back into it.

The greatest density achieved by water molecules is at 4Â°C. It is recommended for future laboratory performers to measure the actual room temperature before, while, and after conducting the same experiment, to make sure that the temperature is constant all throughout. We were added Niacin solutions their concentrations; 4, 8, 12, 16 % one by one.

The results also identified an experimental density of 7. Therefore, the experiment's computations indicate that density describes a material more accurately than weight. Task 3 Alkalinity of natural water. It is important for this information to be correct because other scientists will rely on the value of this number for a variety of purposes. Methods A 50 ml graduated cylinder was filled with 20. . Then we determine its apparent mass.
