Calculation

Name: Julia Bland Lab Section: Tuesday A.M. (11:30) TA’s Name: Yuogi Date: October 15th Course: CHEM 1001 Abstract: Avogadro’s number is one of the vital constants in the chemistry world, used in a multitude of experimental and theoretical calculations. This lab endeavours to experimentally measure Avogadro’s number by adding drops of stearic acid into a known area of distilled water, and using this data, calculate the molecules in the monolayer. The experimental value of Avogadro’s number…

settlement period is usually preferred, as a delay in receiving funds can place strain on an organisations abilities to meet its obligations. Effective management of accounts receivable minimises the risk of bad or doubtful debts. The efficiency calculations completed for GWA (Appendix *), show the average settlement period for accounts receivables was 73.5 days for the period. As illustrated below in Figure *, the settlement period was relatively stable at 73 days in 2011 to 71 days in 2012 and…

Purpose: The purpose of this lab is to prove and discern the empirical formula of copper oxide using the Law of Conservation of Mass. This states that in measuring the mass of each component of copper oxide and determining the percent composition of each the copper and the oxygen within copper oxide it is possible to find the ratio of the elements within the compound. Procedure: In order to conduct this lab, 25.1mL of distilled water then 25.5mL of 3M HCl must be added 2.11g of copper oxide.…

Calculation for baseline: CRG weights for the prior contract year times prior year revenue by rate group and county 2. Contract year membership equals baseline membership o Accordingly, the true-up will measure CRG weights, membership, and revenue for the contract year o Decrease revenue pmpm by 4.75% for “pass-through” dollars; this is a globally calculation for all rate groups o Addition of HCRA at 7.04% for facility claims only…

Every person has an specific amount that they are worth. Net worth is the calculation of your amount of property and money you own subtracted by the debt you owe. Although finding your true amount you are worth may be hard because most people would not sell everything they own. There is an easier way to find your finances to calculate an estimate of your total value. This is vital to know because it shows you where you stand financially. This is most important when you are making big and…

intelligent with her numbers. Katherine Johnson was also the third African American to earn her PhD in Mathematics. Katherine Johnson contributed to space exploration by working backwards to make project mercury a success, Johnson also worked on the calculation that allowed the Apollo astronauts to return home from the moon, and to look at the black box data from crashed airplanes. To begin with Katherine Johnson once worked backwards to make mercury a success which was one of her…

figures in this calculation was to look at the experimental value in the two equations, which is the mass. The mass had 3 significant figures and the answer must have the same number of significant figures as the experimental value in this calculation. 3. When the anhydrous sample was rehydrated, only 93.4% of the sample could be recovered. This was because some of the mass of the sample remained stuck to the filter paper and could not be measured in the final mass calculation. This…

water and percent of copper can be calculated with the masses that were taken before and after the reaction. The calculations of the percent of water and copper are shown below: Water: 5H2O:(2.194g3.385 g)*100 64.814% Copper: Cu:(1.104 g3.385 g)*100 32.614% When finding the theoretical percent of water and copper one can find the molar mass of each and find the percent. The calculations are shown below: Water: 5H2O:(90 g153.546 g)*100 58.614% Copper: Cu:(63.546 g153.546 g)*100 41.356%…

Kaufman, 2004) to “evaluate the equivalency of both groups on fluid intelligence”. In the Chi-square process, the results showed that bilingual kids had a higher calculation on chi-square that monolingual kids. The validity of these calculations can be valid. I did my best to complete each step of the chi-square correctly. With the calculations made, i can agree with my hypothesis that bilingual kids do have a better memory recall than monolingual kids. Although these results were from 5 year…

Library (GSL) (http://www.gnu.org/software/gsl/). 4.6 Calculation of regional level climate characteristics Regional mean value of each climatic characteristics was calculated for each climatic region (CR), elevation range (ER) and elevation range within climatic region (ERCR) as simple arithmetic mean of all interpolated values within the calculation region. Considering only spatial autocorrelation between two grid points within a calculation region, the uncertainty of the calculated regional…
