Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes
Objective:
In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment, it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due to different numbers of neutrons in the nuclei. From this lab, I expect that we will be able to separate the candy, and be able to find the atomic mass by weighing the candy and finding the mass of it.
Procedure:
The materials needed for this experiment include: 3 different types of candies (M&Ms, Mentos, and My Mint), paper and pencil for recording data, and a digital balance in grams. The following discussions will be showing the steps for the procedure. The first step is to sort the 3 different types of candies (atoms) into 3 different isotopes. Secondly, we have to count all the atoms of each isotope and record the numbers …show more content…
Data:
My group’s data (Bobby, Prim , and me) Type of atom | M&M | Mentos | MyMint | Total | Total number of atoms | 12 | 3 | 4 | 19 | Total mass of Atoms | 10.36 g | 8.29g | 11.55g | 30.2g | Average mass of one atom | 0.86g | 2.76g | 2.89g | --------------- | Relative abundance(%) | 63% | 16% | 21% | 100% | Relative Mass | 0.54g | 0.44g | 0.61g | ----------------- | Average Atomic Mass of Candium | --------- | ---------- | ----------- | 1.59g | Class average atomic mass for Candium | ---------- | ------------ | ------------ | 1.65g |

Class data Groups | Average atomic mass of Candium for each group | Group 1 | 1.63g | Group2 | 1.64g | Group3 | 1.64g | Group4 | 1.64g | Group5 | 1.66g | Group6 | 1.59g | Group7 | 1.73g | Group8 | 1.65g

    E Faecalis Lab Report

    In the experiment involving varying pH levels, E. faecalis, S. epidermidis, L. lactis, and L. casei were subjected to different pH levels and then were allowed to incubate in order to determine the minimum, maximum, and optimum pH levels for growth of specific bacterial species. It was found that lower pH levels between 2 and 4 inhibited or promoted little to no growth for E. faecalis, S. epidermidis, and L. casei. It is evident that these bacteria were resistant to alkaline environments, however, it should be noted that certain mechanisms must have been acquired or involved in maintaining equilibrium within the bacterial cell. High alkalinity generally leads to physiological problems within microbes including the disruption of plasma membrane…

    Aspect 2: In our investigation of the Atomic laws we had some major results in all 3 experiments. In the Conservation of Mass Lab, we found that the total combined mass was equal to the original individual masses of the substances. In the Oreo Lab, our ratio result was 2:1. We found that the double stuf is truly (approximately) double the amount of a regular Oreo’s filling. In our final Crucible Lab, our major result as partners was the percentage of oxygen was measured to be 40%. The class' average was 41.3%, when we should have had 39.17%.…

    Yeast which is also known as Saccharomyces Cerevisiae is a unicellular eukaryotic Fungi means that is made up of one cell with a nucleus(“What is Yeast”).Yeast is a very practical product that is used in mainy way like when baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose,Lactose,Sucrose,and Starch.The main thing that make some of these carbohydrates different from each other is if it's a Monosaccharide, Disaccharide,or Polysaccharide. Monosaccharide are basic sugars…
