Sep-Dec 2007 University of British Columbia Okanagan - Engineering 17/09/2007 1 THE DENSITY OF LIQUIDS AND SOLIDS Pre-lab assignments (on engineering paper or regular graph paper) 1. A solution of the simple sugar, fructose, in water is 20% fructose by mass, and has a density of 1082 kg/m 3 . How many grams of fructose are in 45 mL of this solution? 2. The dimensions of a block of copper are 5.0 in x 3.0 in x 2.0 in. The density of copper is 8.92 g/cm 3 . How much does the block weigh (a) in grams, (b) in pounds? Introduction In this experiment the density of a liquid will be determined by using different pieces of volumetric glassware to measure out a known volume of the liquid and then determine the mass using an analytical balance. The density of a solid will then be determined by weighing the solid, followed by measuring the volume of liquid the solid displaces. The experiment is designed to familiarize the student with the fundamentals of uncertainties and error analysis, as well as to introduce the important laboratory techniques of weighing and using volumetric glassware, Equipment - 10 ml pipet and pipet bulb - 15 ml weighting bottle with lid/stopper - 50 ml burette - 25 ml volumetric flask with stopper - 50 ml elrenmeyer flask and cork - 10 ml, 50 (or) 100 ml graduated cylinder - 50 ml, 100 ml, 250 ml beakers - Ring stand/Stand for burette - Analytical balance - Micrometer Procedure The experimental data should be recorded on the Observations/Report sheet. Gloves and eye protection must be worn. Part 1 Liquid Density 1 1. Using an analytical balance weigh a dry weighing bottle & lid. 2.
