Experiment 1 Lab Report Determining the Densities of Liquids and Solids OBJECTIVE: The objective of Experiment 1 was to find the density of an unknown liquid and an unknown solid. DISCUSSION: Density is a standard physical property of a liquid or solid.

Description. This lab helps drive home the point of "density is mass divided by volume." It shows students what happens when they change volume but keep mass constant, when they change mass but keep volume constant, and when they change both of them. It also introduces them to the Archimedes method of finding the volume and density of an object.= 0. 449/m 1. 01 1. 05 1. 00 1. 04 spgr = r substance (9/mL) density of water (1 . 00g/m2) 32 Laboratory Manual for General, Organic, and Biological Chemistry C.

Laboratory observations in chemistry, as in other quantitative sciences, often involve making measurements and then using these measurements in calculations. This week's measurements of mass and volume followed by calculation of density is an excellent first example. We will also consider what we can do with a density once it is determined.Since density is a physical property, it can be used to determine the identity of a substance, as you will do today. To calculate density (d), divide the mass (m) of the object by its volume (V). The most common units for density in chemistry are g/cm3 for solids, g/mL for liquids, and g/L for gases. m.Calculate density, and identify substances using a density chart. Density is a measure of the amount of mass in a certain volume. This physical property is often used to identify and classify substances. It is usually expressed in grams per cubic centimeters, or g/cm3. The chart on the right lists the densities of some common materials.Density: A Characteristic Property Lab. Pre-lab Questions: Use the background information in the lesson and the video to help you answer these questions before the lab. 1. What is the purpose of this lab? (5pts) 2. What is density, and what two variables must you know to calculate density?The densities of solids and liquids are expressed as g/mL or g/cm ^3. For gases the g/L unit is favored since their densities are usually smaller. When a substance has a density less than that of water (1.00 g/mL) it will float and when the density is greater than the density of water, it will sink.Aug 5, 2017 ...
