Volume One

the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml or g/cm³. This lab will focus on measurements. Mass and volume are physical properties that can be easily measured. In the lab, the mass was measured in grams and the volume was measured in ml. Limitations on results The percent error when

more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since the density of an object may be found using its mass and its volume. The experiment yielded two different density values, however when error analysis was conducted, the water displacement method was proven to be more accurate. INTRODUCTION

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data

It used mass, temperature, length, volume, density, and making a dilute solution. I learned the importance as well as the difficulty of making proper measurements in a lab setting. If one measurement is off, it will throw the entire equation off. This will give either incorrect or inaccurate results. Questions: A. Water boils at 100°C at sea level. If the

Contrasting Liquid Volumes to Determine Precision and Accuracy of Experimental Measurement Introduction The purpose of this experiment is to compare and contrast liquid volume reading values of different measuring devices, determining the precision and accuracy of experimental measurement. This was done through use of a graduated cylinder, a serological pipette, and a variable volume pipette. In laboratories, many kinds of containers and devices are available for measuring liquid volume. For example

Objective Objectives will be calculating densities of regular solids, determine the densities of solutions by plotting mass versus volume. Predict whether objects will sink or float in different solutions based on the densities of the solutions and objects.

review use of electronic balance. Next learn to calibrate the glassware. Than learn to use a volumetric flask. After that learn how to determine density. Finally learn how to calculate percent error. It is known that density equals mass divided by volume which is a simple formula that gives half of the desired information. The equipment that was used for this experiment was the Graduated cylinder and the Volumetric flask. Introduction The scenario is that you are a chemical engineer for the Podwitz

mass and volume from the small pieces of clay from all three trials and I find the average which is 14.7g (mass) and 8.7cm3 (volume). Then I divide using thee formula d=m/v and for density I got 1.7g/cm3, rounded to the nearest tenth. Next I did the same for medium of all three trials in which I got 22.5g for the average of the mass and 13.3cm3 for the volume. I divide using the same formula and also got 1.7g/cm3, rounded to the nearest tenth. Lastly I find the average of mass and volume for large

concept of buoyancy. The volume of water that your body displaces has weight. The weight of the displaced water pushes upward on you, while the weight of your body pushes down. If the weight of the displaced water pushing upward is greater than your weight, then you will rise out of the water to a point where equilibrium has been achieved. This means that the weight of your body that is submerged in the water, let’s say from your shoulders down, is equal to the weight of the volume of water that your body

Let’s assume we have a cube with a volume of 1cm3. Each side of the block equals 1cm. Picture a die for each cube. 1. How many sides does a cube have? 2. Let’s use 1 block to represent a small cubed organism and 8 blocks to construct a large cubed organism. Complete the following table. Total Volume Total surface area Surface area:volume
