Compare The Density Of Water And Unknown Liquid

because each of the objects displaced the water by 1 mL, their mass over that mL is their density.

Mole of chlorine : 1.0217g - .221g - .3946 g = .4061 g of chlorine

The blue object has a density of 1.19g/cm3, while the black object has a density of 1.41g/cm3, and the clear object has a density of 1.04g/cm3. Although the density difference is in the tenths it still is a difference in the densities. For example, the difference in the density of neon versus sodium is 0.03 which is a small difference and because of the different densities the two substances are completely different. The measurement of the volume in mL could have been better if the 10mL graduated cylinder was used in place of the 50 mL. The calipers and graduated cylinder only measures to the tenths which does not give as precise measurements as the balance. The human error causes the non-identical cm3 to mL measurement of the same objects causing a slight difference in the densities of the same object. When comparing my data to another group doing the same experiment I found a possible miscalculation of volume in mL for the clear object in my own experiment. Aside from the possible miscalculation, the volume measured in the other group was to the ones place of a number while our group measured to the tenths place. Since the top loader balance the other group used was different, the masses were also different in the hundredths. They also stated that the objects are made of the same material which according to their data is not

Density was an important part of this lab. Density can be defined as the ratio of the mass of an object to the volume. To find the density of an object, simply divide mass and volume. The equation looks like this: D=M/V. Density is an intensive property that depends only on the composition of a substance, not the size of the sample.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

I will be doing this experiment to understand density of water compared to the volume of an object. D=m/v=mass/volume

5. Calculate the mass of the water by subtracting “Mass A” from “Mass B.” Record the mass of the water in Data Table 4.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

2. In order to calculate the density of a solid or liquid sample, what measurements are needed?

The purpose of this lab is to learn how to perform a lab, to learn how to measure mass and volume, to understand additive and non-additive properties, and to define density.

Our IA demonstrates the relationship between buoyancy and liquids of different densities. As competitive swimmers, we are always striving to find the ideal conditions to swim in. The idea that different densities of liquids could affect the buoyancy of the objects in the liquids immediately sparked an interest to us. What would happen if the pool we swim in was full of rubbing alcohol or vegetable oil instead of water? What would happen to the buoyancy of the objects in the pool? We placed a 200 kg weight in water, rubbing alcohol, olive oil, corn syrup, and dish soap. All of these liquids have different density. We found that generally the more dense a liquid is the more buoyant the weight is.

The experiment begins with massing 2.0g of SPA in a weighboat. In a separate weighboat, mass 0.50g of NaCl. Then, fill a 200ml beaker with 175ml (175g) of tap H2O.

The object of this experiment was to determine the density of a fluid by performing three different methods and use that determined density to calculate the surface tension of the fluid.

Another set of experiment was carried out as described in experiment B but the mixture in calorimeter was substituted with 100 cm3 of distilled water.
