Finding Density Density is defined as mass per unit volume‚ which can be used to determine the object or substance observed. Many people use the density of objects to find what it is and how to classify the object. The object of the lab conducted was to find the density of the substances given and to find what the unknown liquid and solid were. The process to finding what the unknown solid and liquid were‚ was to find the density and to conduct multiple trials so when the density

Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a density calibration graph‚ used

Experiment 5 Liquids and Solids Chemistry 1211 Fall 2012 Section 1: Abstract‚ Experiment and Observation Abstract: The purpose of this experiment is to determine the boiling point of a liquid and the melting point of a solid. We also were able to observe the difference between boiling and melting point Experiment and Observation: We used isopropyl alcohol and set up an experiment to observe the boiling point. We set up a second experiment using acetamide to determine

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

LAB REPORT # 1 DENSITY DETERMINATION CHEMISTRY 100 – 04 INTRODUCTION: The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density. PROCEDURE: 1) Obtain a solid metal 2) Weigh the dry sample carefully to

Density of a given substance is independent of volume. Density never changes. I know that for a fact because during the “Density Does Not Change With Size” lab‚ we measured the length of rods given to us. For one I got 4.2cm‚ and when i weighed it on the scale I got 14.5g. Once I put the rod in the graduated cylinder I got 5.5cm squared. But when you divide your mass by volume‚ you will get your density. And for the density I got 2.6g/cm squared.Then for the other rod I got 6.7cm for length‚ 23.2g
