DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise

Measurement of the Densities of Water and Alcohol Phuc Truong and Shane Steele Data Collected: September 8‚ 2014 2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass

Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper
