Daniel H. Perry Procedures of Measurement and Density of Sugar in Soda Introduction The main focus of this lab was to acquire a basic understanding of how to properly use measuring devices in order to determine properties of a liquid. These properties are volume‚ mass‚ and density. The following measurements were obtained in the lab: density of water‚ both density and concentration of aqueous sugar solutions‚ and density of various soft drinks with respect to sugar. Additional experience was

method would consistently test the foam and ensure it has the correct density? Background: There are words that need to be understood before executing the experiment. The first thing you need to know is density. Density is a measure of mass per unit of volume. The reason for testing density of doors because doors must contain a density of 14.34lbs per ft3 of foam‚ or it will collapse if the density is too high. If the density is too low‚ it won’t allow for normal expansion during weather changes

experiment concerning Archimedes’ Principle to determine the density of solids and liquids using Archimedes’ Principle. For the density of solids‚ they had made use of spring balance to measure the mass of the metal samples‚ which were tied via string‚ in air and when immersed inside a 2000mL beaker‚ where H2O lies. They had computed the density of each sample metal using the formula: ϱs = maϱw / ma - mw and computed a percentage error. As for the density of liquids‚ they had filled a graduated cylinder with

Part I: Density of Unknown Liquid Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1: Empty graduated cylinder is 25.5 subtracted from 36.5 of the liquid and the cylinder combined equals 11 grams of liquid. Trial 2: 36 grams of water and liquid combined minus the 25.5 of the empty cylinder means equals 10.5 grams of liquid only. Trial 3: Again 36 grams of liquid and the empty cylinder

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

Also‚ pulsars are highly regular astronomical clocks. Density varies with temperature and pressure. It would be necessary to measure both mass and volume very accurately in order to use the density of water as a standard. People have
