Experiment 1 Density By Jessica Schmidt Chem 112L-S23- Athukoralage Gunawardana September 20, 2016 Erin Whitehouse The first part of the experiment consisted of finding the accuracy and precision of three different measuring devices, a 50mL beaker, a 25mL graduated cylinder and a 25mL pipette. The mean volumes and uncertainties were found to be 22.5mL 1.9, 23.72 .25, and 24.89 .43, respectfully. The 25mL pipette was found to be the most accurate out of the three. The density of water was found to be 0.9979 g/cc with a percent error of .08, while the known density of water being 0.997041 g/cc. For the second experiment, the mean found density of copper was 8.7g/cc .22 and the known density for copper is 8.92 g/cc with a percent…
Objective- Our goal for this lab was to calculate the Density of a substance. We needed to make sure we had the materials to find mass and volume and then use a formula to calculate density. Introduction- The main principle of this experiment was to figure out the Density of certain objectives given to us in the lab. We had to know the the formula D-M/V in order to find the density of that object.We also needed to know the density of water(1.0 g/l) in order to predict if something would float…
Introduction and Theory: The lab conducted was to investigate the density of not only copper but also diet and non-diet soda. Techniques used in the experiment included water-displacement, measuring copper’s dimensions, and using volumetric pipettes to measure out specific soda volumes. Beginning Question(s): How does the use of two experimental methods, improve the chances of calculating the density of copper? How does the density of non-diet soda compare to that of diet soda measured at…
Density of Sand The objective of this lab is to use knowledge from previous labs, like the density of water and solids lab, and apply it to find the density of sand. First you must weigh your graduated cylinder, and record the weight, then pour in whatever amount of sand you choose. You then must weigh that to find the mass, and subtract whatever you got by the mass of the graduated cylinder. After that you pour in some water, and find the difference of how much the water went up and, what the…
introduction to the Balance and the Determination of Density Purpose: To make measurements and collect data to determine the physical properties of matter; density, volume, and mass. Materials: Graduated Cylinder Balance Water Unknown Liquid Paper Towels Weighing Paper Weighed Solid (Rubber stopper) Procedure: Part A Obtain a 10 ml graduated cylinder and measure its mass on the balance. Record. Pour water inside the graduated cylinder. In other to get the correct measurement of volume, read…
Density Open Response Density Density is the mass per unit of volume of a substance. Density is measured in grams per milliliter (g/mL), or grams per centimeters cubed (g/cm3). The density of an object is what causes it to sink or float. If an object has higher density than the liquid it is being placed into, it will sink. If an object has a lesser density than the liquid it is being placed into it will float. For example, the density of…
The Relationship between Mineral Type and Density (g/ml) Purpose/Introduction: The purpose of this lab was to understand the relationship between minerals and density, the ratio of mass to volume, particularly, how density can be used to identify mineral type. In the lab, two samples of the mineral, feldspar, were measured for mass and volume in order to calculate their density. Many of the mineral tests yielded qualitative data, such as color, streak, luster, and crystal shape, which can be…
Prior to the lab, I proposed three questions in regards to density. The first question inquired which method of density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end. In the first half of the experiment, the density…
determine the density of an unknown liquid. Additionally, the opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing the mass (g) by the density), the calculated density was then compared…
as 7% of the world's renewable fresh water. According to these two sets of data, it is inferred that Canada is a rich country; if not in wealth, the country is rich in resources. The size and the amount of water in Canada pose noticeable impacts to both the personalities and also the state of living for the inhibitors in either positive or negative ways. People tend to be more isolated when approached due to population density, there is a reduction of stress whether due to economical earnings or…
