Laboratory Techniques and Measurements (adapted from Labpaq Version 09.1.06 by Peter Jeschofnig‚ Ph.D.) Experiment Summary You will have the opportunity to learn how to conduct measurements in mass‚ volume‚ and density using scales and common laboratory equipment. Review the safety materials and wear goggles when working with chemicals. Read the entire exercise before you begin. Take time to organize the materials you will need and set aside a safe workspace in which to complete the exercise

ratio of mass per unit volume. It is an “intensive” property‚ that is‚ it does not depend on the amount of the substance. The density of any material is determined by measuring its mass and volume and then dividing the mass by the volume. The mass of a substance can be measured directly using a balance. The volume of a liquid can also be measured directly using special laboratory glassware‚ such as a graduated cylinder‚ a buret‚ or a pipet. In this experiment‚ liquid volume will be measured using

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 for mass‚ 9cm squared for volume‚ and for
