Volume and Data Table Essay Example

water slowly. Be sure the metal cylinder is completely submerged. Record the new volume to the nearest 0. 1 ml in the data table.

The values are measured in grams per cubic centimeter (g/cm) or grams per milliliter (g/mL). The volume of the cylinder is determined through water displacement, while the volume of the metal cylinder is calculated using a formula. To find the percent error for each item, compare your measured values from analysis 1 with the accepted values from analysis.

Please demonstrate all calculations to ensure correct significant figures are used.

A metal cylinder is measured using water displacement.

Identify the potential error sources. 6. The students were asked to determine the density of a brownie. Johnny opted to consume h of his brownie. How would Johnny's findings compare to those of the rest of the class?

Provide an explanation.

1. Describe In detail now you would determine rage to fit into a graduated cylinder. Or app t TA o Tanat Is o Read the entire laboratory investigation and the relevant pages of your textbook. Then answer the questions that follow.
2. What two properties of matter are used to determine its density?
3. What pieces of laboratory equipment would you use to measure the properties needed to determine the density of a substance?
4. Using the properties stated in question 1, write the formula for density.
5. What two sets of units can be used to describe density?
6. Why are they interchangeable?

The volume of a cylinder can be calculated using the formula:

The volume (V) of a cylinder can be determined by using the given height (h) of 3.52 cm and radius (r) of 0.89 cm. Both a pound of feathers and a pound of lead weigh the same, one pound. However, there is a clear distinction between a small piece of lead and a large bag of feathers, despite having the same weight. This distinction is expressed through density, which is defined as the ratio of an object's mass to its volume.

In this laboratory exercise, you will use your previous skills and techniques to identify different substances. The formula for density (g/ml) is Mass (g) divided by Volume (ml). To determine the accuracy of your technique, you will calculate the percent error by comparing the measured value with the accepted value.

The liquid volume is measured from the lower part of the meniscus.

1. Record the water level to the nearest 0. 1 ml in the data table.

Mass the cylinder with 50 ml of water.

Using the water displacement method, record ten measurements of mass to the nearest 1 gram in the data TA Volume.

1. Fill your 100 ml graduated cylinder to approximately the 50 ml mark.
2. Record the volume to the nearest 0. 1 ml in the data table.
3. Tilt the cylinder and slide the metal cylinder into the water slowly. Be sure the metal cylinder is completely submersed.
4. Record the new volume to the nearest 0. 1 ml in the data table.
5. The volume of the metal cylinder is the difference between the two water levels.
