Density Of Metals Lab
Density of Metals
Problem: How does the mass and volume help determine the density of known metal samples?
Hypothesis: When comparing the density of Zn(zinc) and Cu(copper), you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v.
Materials:
* 2 metals (options: zn, al, or cu) * 3 samples of each metal (small, medium, and large) * Scale/Balance * Calculator * Water * Graduated Cylinder
Safety:
* Be prepared for your work in the laboratory. * Read all procedures thoroughly before entering the lab and/or starting experiment. * Be alert and proceed with caution at all times in the lab.
Step by Step Procedure: 1. Wash hands with soap and water 2. …show more content…
Zinc % Error = ǀ 4.115 – 7.13 ǀ x 100 = 311.5 7.13
Copper % Error = ǀ 6.954 – 8.96 ǀ x 100 = 595.4 8.96
In this lab the problem answered was how does the mass and the volume help determine the density of known metal samples. To find the density of known metal samples we used the mathematic formula D=m/v. To find the mass you put each sample of each metal onto a balance/scale and to find the volume you used a graduated cylinder filled with water up to 180mL and you then put each sample of each metal into the graduated cylinder. The amount the water rose was the volume of the metal sample. Copper,as said in the hypothesis was proven to have a greater density over Zinc
Conclusion:
In this experiment we found that the density of Zinc and Copper and can be determined by using the density formula and then compared with each other the results showed that Copper was a greater density. Something that could have been done better in this experiment is that we could have made sure there was an even amount of each sample for each metal. We could have also tested aluminum along with Copper and Zinc. In the end, however, Copper still would have the greater
