The Density of Water Using the electronic balance, obtain the mass of your mL graduated cylinder. In order to find the density, I simply divided the mass found by the volume found.

Use your thermometer to record the temperature of the water in your graduated cylinder. For example, the precision for the water was found by this equation: The equation for the water was 0.

Carefully add all the aluminum pellets to the water, making sure not to lose any water to splashing. Use these measurements along with the density of aluminum to calculate the thickness of the foil. Then take the average of these three density values.

Next 18 Sep A few drops of the liquid inside seemed to drip out from right above the bottom where it was supposed to come out. He scrapbooks yonder every minute or three.

A precision of Tilt the graduated cylinder and allow the pellets to gently slide to the bottom. Graphical Analysis of Mass and Volume Data of an Unknown Solid Check out a ruler from the stockroom and obtain a tube containing cylindrical pieces of an unknown solid material from your instructor.

My precision was 1.

Measure the new volume of the water plus the pellets. Add another mL of distilled water to the graduated cylinder.

I subtracted the intial amount of liquid in the buret from the final amount of liquid in the buret. This academia was first published 25 Sep and last revised 13 Feb Finally, look up the true density of water at the temperature used, and evaluate the accuracy of your average density value by calculating your percent error.

Transfer all the pellets to the beaker, and measure the mass of the beaker and pellets. When finished, retrieve and dry the aluminum pellets and return them to your instructor. My data from the unknown substance turned out incredibly well.

My accuracy was also high, as my error was only 0. This same method was used to find the volume of water in the flask.

The Thickness of Aluminum Foil Now obtain a rectangular piece of aluminum foil from your instructor. However, my accuracy turned out to be very high, as my error was very low. In the end, my data was fairly accurate with the actual data, so the experment was a success.

Again, precisely measure this volume of water, and then measure the combined mass using the electronic balance. This difference was how much liquid was dispensed. Replace all the objects in the tube and return the tube to your instructor.

Record the ID Code of the unknown solid on your report form. Measure the mass of the foil using the electronic balance. Use the ruler to measure the length and width of the piece of foil.

Then measure the combined mass using the electronic balance. Therefore, I should be even closer to the actual density. Calculate the slope of this line, which is the density of the unknown solid.

A sample equation would be Precision was found by taking the absolute value of the highest density minus the lowest density, dividing that difference by the average density, and then multiplying that answer by Again, start with the smallest object first and progress in order of increasing object size.

An example would be Start with the smallest object first and progress in order of increasing object size.View Lab Report - Lab #1 - Density of Solids and Liquids from CHEM at Cornell University.

Results and Discussion The density of an unknown liquid was found using the difference method. First,%(5). By weighing these liquids, you will find that density and weight are closely related.

Safety Information Lamp oil is a flammable liquid and must be handled with care. The Density of Liquids and Solids Objectives The objectives of this laboratory are: a) To determine the density of pure water; In Part A of this lab, the mass and volume of distilled water will be measured in order to determine the Record the ID Code of the unknown solid on your report form.

2. Using the ruler, measure the dimensions. General Chemistry I (FC, 09 - 10) Lab # 1: The Densities of Solids and Liquids Revised 8/19/ 1 The density of a material may be defined as mass per unit volume.

Pre-Lab Report Density of Liquids and Solids. PRE-LAB REPORT Lab: Density of Liquids and Solids Purpose of the experiment: The purpose of this lab is to help understand how to resolve the density of liquids and solids.

Pre-laboratory Assignment: The Density of Solids and Liquids.

Circle the correct responses in the following statement: Density is a physical / chemical property of matter and an intensive /extensive property of matter.

What devices will you use to measure the mass and the volume of water in Part A of this lab?
