The sample essay on Density Lab Report Chemistry deals with a framework of research-based facts, approaches, and arguments concerning this theme. To see the essay’s introduction, body paragraphs and conclusion, read on.

We then placed a sample of Copper in the graduated cylinder. 2. The water level rose ml. We subtracted the original ml of water from the ml of water with Copper in it. This gave us the volume of the Copper, being ml. 3. We then took the sample of Copper and placed it on the Triple beam Balance.

4. We recorded the mass of the sample at 13. 8 g. 6. Then we divided the mass of the Copper by the volume. This giving us the density of the sample being 4. 6 mug. 7. We found the %error to be 48. 4%, by 1. We then placed a sample of Lead in the graduated cylinder. 2. The water level SSE ml.

We subtracted the original ml of water from the ml of water with Lead in it. This gave us the volume of the Lead, being ml.

3. We then took the sample of Lead and placed it on the Triple beam Balance. 4. We recorded the mass of the sample at 84. G. 6. Then we divided the mass of the Lead by the volume. This giving us the density of the sample being 14. 12 mug. 7. We found the %error to be 24. 5%, by Unknown (Magnesium) 1. We then placed a sample of the unknown metal in the graduated cylinder. 2. The water level rose ml. We subtracted the original ml of water from the ml of water with the unknown substance in it.

This gave us the volume of the unknown metal, being ml. 3. We then took the sample of the unknown metal and placed it on the Triple beam Balance. 4. We recorded the mass of the sample at 14. Egg. 6. Then we divided the mass of the unknown metal by the volume. This giving us the density of the sample being 1. Ml/g. 7. We found the %error to be 9. 2%, by subtracting our result minus the accepted value of the sample, multiplied by Results Calculation questions Zinc calculations Volume- We found the volume by placing the Zinc in a graduated cylinder filled tit ml of water.

We observed that the water level rose to ml. We then subtracted the original ml from the ml that contained the Zinc. This gave us the volume, being ml. Mass- We found the mass of the Zinc by placing it on the triple beam balance. This gave us the mass, being 36. G. Density- We found the density by dividing the mass by the volume. 36. G divided by ml. This giving us the density, being 9. Ml/g. %Error- We found the % error by subtracting the density (9. Ml/g) from the accepted value (7. Egg), Multiplied by 100%, then divided by the accepted value.

This giving us the %Error, being 27. 8%. Copper calculations Volume- We found the volume by placing the Copper in a graduated cylinder filled with ml of water. We observed that the water level rose to ml. We then subtracted the original ml from the ml that contained the Copper. This gave us the volume, being ml. Mass- We found the mass of the Copper by placing it on the triple beam balance. This gave us the mass, being 13. G. Density- We found the density by dividing the mass by the volume. 13. G divided by ml. This giving us the density, being 4. Mug.

Error- We found the % error by subtracting the density (4. Ml/g) from the accepted value (8. Egg/CM), Multiplied by 100%, then divided by the accepted value. This giving us the %Error, being 48. 4%. Lead calculations Volume- We found the volume by placing the Lead in a graduated cylinder filled with ml of water. We observed that the water level rose to ml. We then subtracted the original ml from the ml that contained the Lead. This gave us the volume, being ml. Mass- We found the mass of the Lead by placing it on the triple beam balance. This gave us the mass, being 84. G.

Density- We found the density by dividing the mass by the volume. 84. G divided by ml. This giving us the density, being 14. Ml/g. %Error- We found the % error by subtracting the density (14. Ml/g) from the accepted value (1 1. Egg/CM), Multiplied by 1 00%, then divided by the accepted value. This giving us the %Error, being 24. 5%. Unknown calculations Volume- We found the volume by placing the unknown metal in a graduated cylinder filled with ml of water. We observed that the water level rose to ml. We then subtracted the original ml from the ml that contained he Lead.

This gave us the volume, being ml. Mass- We found the mass of the unknown metal by placing it on the triple beam balance. This gave us the mass, being 14. Egg. Density- We found the density by dividing the mass by the volume. 14. Egg divided by ml. This giving us the density, being 1. Mug. %Error- We found the % error by subtracting the density (1. Ml/g) from the accepted value (1. Egg/CM), Multiplied by 100%, then divided by the accepted value. This giving us the %Error, being 9. 2%. Data table and Observations Sample Mass Volume Density % Error

Accepted value 36. G mm L 9. Mug 27. 8% 7. Egg/CM 13. G ml 4. Ml/g 48. 4% 8. Egg/CM 84. G mm L 14. MGM 24. 5% 1 1. Egg/CM Unknown (magnesium) 14. Egg ml 1. Ml/g 9. 2% 1. Egg/CM Written response questions 1. What is your unknown? How do you know? The unknown is magnesium. We know this density we recorded is very accurate to what we got. 2. Is density a physical or chemical property? Explain. Density is a physical property because the substance can change when the substance changes state. 3. Is density an extensive or intensive property? Explain.

Density is intensive because it doesn’t depend on a mass. Conclusion In this experiment we found mass, volume, density, and %Error. To find volume we used a graduated cylinder with ml of water and placed the different metals in it to see how much the water level rose. To find the mass we used a triple beam balance. To find the density, we divided the mass by the volume. To find the %error we subtracted the density we found from the actual density then multiplied that by 100%, then dividing that buy the accepted value. The error in our experiment most likely came from miscalculation.

There were any parts in this experiment that we could have slightly miscalculated. In this experiment we learned to calculate density and %error, using volume and mass. We learned that we will have error in our experiments. We also identified an unknown metal as magnesium, by using measurements we found and some that were given. Table of contents .
