Experiment 1 Density by Lindsey Loerzel Chem 112L-S10---Machelle Martinez September 9th, 2014 Reed B The volume delivery accuracy and precision of different forms of glassware were found by volumetric measurements and density of a metal was determined by testing the mass of water in different glassware and calculating the volume, which was compared to the known. The density of the metal was found by volume displacement. The known volume of one gram of air saturated water at 25 degrees C is
from this Lab, they must know what density, mass, and volume are and know the comparison to teach other. Mass is the amount of matter in an object and volume is the amount of space that object is occupying. Density is the amount of mass in a given space, which is mathematically defined as mass divided by volume. Problem: How can you use density to determine the identity of materials? Objective: The purpose of this lab is to identify materials using density Hypothesis: In this lab I think we
was born out of a curiosity to measure the density of each object. To start, we looked at the generally accepted figures of density for each object. This led us to think that metal, in most cases, should be more dense than the rest of our objects. We then began to decide how to verify or disprove these figures based on the differences in materials used from the benchmark objects. This allowed to form our question and begin our calculations on the density of each object. Each measurement is listed
creating a density rainbow. However, during the creation of the density rainbow, two of the blocks stuck together and broke the seal between two colors, causing the colors to blend together. Introduction: Density is the amount of mass per unit volume, or how solid an object is. Density is found by dividing mass by volume. Density is very important in life as it determines characteristics of an object, such as if it is able to float or not. Hypothesis: If I correctly calculate the densities, then I
Twinkie Lab Report Having to use the density formula is a factor to use. As a result of seeing how much space is taken roughly around. All that by means take the precise measure of the volume, to designate its quantity. Afterwards, weigh the substance for its mass to complete the method that is needed. Leading towards the formula, density equals mass over volume. Having to have mass and volume, you will need to discover the density. One without the other you will need to find the its missing component
Gianna Munoz & Nicky Quintana 7th Period #8 9-27-15 Density of Metals - Shot Lab Purpose: The purpose of this lab is to determine the density of two unknown metals. Materials: • Metal Shot • Wash Bottle • Electric balances • Calculator • Graduated cylinders • Water • Sieve • Weigh boats Pre-lab Questions: 1. What is the volume of the water in the graduated cylinder shown? The volume of the water in the graduated cylinder is 43.1 milliliters. 2. What is the volume of the metal shot and the
1. There was a correlation between the density’s and the results from this lab. In the first mixture dichloromethane and water were added to a test tube. The top layer was water while the bottom layer was the organic layer. The density of water is less than that of dichloromethane therefore water would go to the top and dichloromethane would be the bottom layer since it has a higher density. On the other hand the second test tube consisted of ether and water because ether is less dense than water
Measuring Mass and Volume Aileen Bautista* and Alexander Garcia CHEM 1A Lab, Department of Chemistry, California State University, Fresno, CA 93740 aileen97@mail.fresnostate.edu October 1, 2015 Experiment 2: Mass and Volume Measurement, was intended to establish proper techniques when obtaining measurements for a set of data collection by examining the results of the collected measurements to indicate the importance of precision and accuracy in order to reduce the amount of error in experiments
Background research What is density? Density is how much mass (g) an object has in ratio to the amount of volume(unit cubed) said object has. All objects have density, but some object are more dense than others if the atoms that make up the object are packed together are more tightly packed together than the atoms in another object. Why do some objects float while others sink? Objects that float have a density of less than 1g/ml. Objects that have a density of more than 1g/ml will not float and
Objectives: The goal of this experiment was to measure and analyze the viscosity for an ideal (toluene/ P-xylene) and non-ideal (methanol/ water) solutions and to understand the differences between them this done by measuring the flow time using Ostwald viscometer. Introduction: Liquid is consisting of molecules layers that arrange one over the other. When we apply a force to a liquid, it flows. While the forces of fraction between the layers offer resistance to this flow. So, Viscosity of a liquid
