Experiment Mass density describes how heavy an object is. Defined by the Greek letter ρ‚ read as rho‚ density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids‚ density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However‚ its CGS units‚ g/cm3 or g/ mL‚ are the most commonly used ones in the laboratory. The conversion is given by 1 gcm3=1gmL=1000

An Introduction to Lab Procedure Purpose: To obtain a higher understanding of lab techniques. Procedure Part A 1- Draw about 400 mL of deionized water into a clean beaker‚ and let it stand for 15 minutes to equilibrate to room temperature. Note‚ there is only one deionized water tap in the lab room; make sure you use the correct tap. 2- Confirm that your 10.00 mL volumetric pipet is clean by filling to above the mark with deionized water and then letting it drain. Your pipet is a

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

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration

The Density Challenge: A Complete Inquiry Activity Introduction Density has been an important part of science for a very long time. Density was discovered by Archimedes‚ a Greek mathematician‚ around 250 BC while determining whether a craftsman had replaced some of the gold in the King of Syracuse’s crown with silver. Density is the compactness of a substance. The new concept of density he discovered was used to expose the fraud. The purpose of this experiment is to make
