Density of the Metal Experiment

What is the purpose of the experiment?

The purpose of the experiment is to determine the density of the metal used.

What steps were taken in the experiment?

The student emptied the flask, dried it, added pieces of metal until it was half full, weighed the stoppered flask and metal contents, filled the flask with water, and obtained the total mass of the flask, stopper, metal, and water.

How do we find the density of the metal?

To find the density of the metal, we need to calculate its mass and volume by subtracting the flask's mass from the total mass and determining its volume via water displacement. Finally, we divide the mass by the volume to obtain the density.

Answer:

The purpose of the experiment is to determine the density of the metal used. The steps involved included weighing the flask with metal, filling it with water, and calculating the total mass to find the density.

In the experiment to find the density of the metal, the student followed specific steps to calculate the mass and volume of the metal. By subtracting the flask's mass from the total mass and determining the volume via water displacement, the student was able to find the density of the metal.

The density of a material is calculated by dividing its mass by its volume. In this experiment, the total mass of the flask, stopper, metal, and water was obtained. By subtracting the mass of the empty flask and stopper from the total mass, the mass of water added with the metal was determined. Using the known density of water (1.00 g/mL), the volume of the space the metal does not occupy in the flask was calculated.

Once the volume of the metal was determined, the density was calculated by dividing the mass by the volume. This calculated density can then be compared to known densities to hypothesize the type of metal used in the experiment.
