Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined

Laboratory Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know‚ identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to

2013 Group No.: 4 Date Submitted: July 17‚ 2013 Experiment #1: Measurements INTRODUCTION Density is a physical property of matter‚ as each element and compound has a unique density associated with it. The unit of Density is g/cm3 or g/mL. It is used to measure thr relative “heaviness” of objects with a constant volume. As defined‚ the formula for Density is Mass over Volume (ρ=m/v) and it can be rearranged to get the Volume (v=m/ρ) or Mass (m=ρv) of a certain substance. The objectives of this

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different
