    In the volume lab, we found that the large graduated cylinder was the most accurate because it had less percent error when measuring the density of water over all of the other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the pipettes in milliliters, the initial mass of the beaker without water in grams, and the final mass of the beaker with water in grams. We did this procedure again, and also tested the temperature of the water with the graduated cylinders, erlenmeyer flasks, and the beakers of the second trial. The first trial, with the 10 milliliters volumetric pipette, showed the volume to be 14 milliliters, 50.78 grams for the initial mass, and 60.68 grams for the final mass. The second trial, with the 5 milliliters volumetric pipette,…

    Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas was…

    Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and…

    density to determine if the slab is the same substance as one of the cubes. In order to do so, the mass of each of the two cubes, and the slab were taken, and the dimensions of each were accurately measured. The dimensions were multiplied to find the volume, and the volume and mass were then used to find a comparable value, the density of each object. The mass and volume of an irregularly shaped stone were then found, and from this, the density of the stone was calculated. The density of the dot…

    For our first model we choose to make four rectangular prisms, and one cube to make a pair of glasses for the two Ping-Pong ball model. We choose these shapes because, we both knew how to find the surface area and volume of them to the point where it wasn’t easy, but it was not super difficult. We felt safe using these shapes. When put together they also can be taped together perfectly to resemble a pair of glasses. We thought that this would be a great model to make because, for one thing my…

    Introduction: 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…
