FIGURES 1 & 2 (6 pts)EXAMPLE CALCULATIONS (10 pts)Post-Lab Discussion QuestionsAnswer the discussion questions in 1-2 complete sentences within the answer boxes provided.1. (4 pts) Post your data on the shared google sheet within 48 hours of the end of lab. (TAs will confirm timestamps.)2. (4 pts) Do the measured density values obtained by the class support the literature values? Use specific numbers from the data tables above to support your answer.3. (3 pts) Considering Figures 1 and 2, what is the relationship between density and temperature?4. (4 pts) Why does density change with temperature? (Consider what is happening at a molecular level.) Explain this in your own words. Do not copy/paste from an external source but instead, include a citation (e.g., paste the url; give the title, authors, etc. to cite a book, etc.), if necessary.5. The coefficient of determination, R2, can range between boundary values of 0 and 1. Values closer to 1 indicate a better fit of a linear trend line to the experimental data points.(2 pts) Consider the density of your samples: Would you predict the data to follow a completely linear trend from 0 to 100 ºC? Why or why not?(3 pts) Based on the data analysis summarized in Table 1, which set of density values more closely follows a linear trend – those experimentally determined or those from the literature? Why?The literature values follows a more linear trend line then the ecperimentally values. This is because the literature values are more concrete and have less systematic error.(3 pts) What does R2 generally represent? How should R2 be interpreted?6. (3 pts) Sources of error. Human error is the error that arises due to the carelessness or inability of the person, e.g., inability to read clearly, spilling solutions, writing down values wrong, etc.). What are other possible sources of error within this experiment? ​​Make two lists – one for systematic errors and one for random errors.Random human errors could be misreading the buret or spilling some of the sample before testing it. Sources of random error could be the temperature in the room or the pressure surrounding the sample which would lead to different data values. Systematic error could come from improperly storage of the balances and themometers leading to uncalibrated instruments.(3 pts) During the experiment, the mass of the water was measured to 4 significant figures. Why is the reported density only given to 3 significant figures?7. Answer the following questions considering the last three columns of Table 2:(2 pts) How well do the measurements of distilled water reproduce the literature values? (Please cite specific data.)(2 pts) Are there significant differences in the densities of the different types of water? Consider the figures, tables, and calculations in your answer, as appropriate.(3 pts) How well do different groups' measurements of the same type of water reproduce each other? ​TA ONLY: Formatting Late PenaltyNameJamoni Collins Partner(s)(2 pt penalty)Jordan Han ONYENJjamoni jinjoTemplate Instructions: Remove and replace any highlighted text.

Answer boxes and fillable tables are provided below for you topresent your data from experiment 1. Include a caption for each figure and a title for each table.Construct figures and fill in tables using your in-lab measurements and recorded data as appropriate. Also include a simple description of the figure data. See notes and examples below.Note on Figure Captions: A proper caption provides enough information about the graph that the reader understands what is being displayed. According to American Chemical Society (ACS) guidelines1, the reader should be able to understand the caption without reference to the text or, in this case, the lab manual. For graphs that include experimental data, include relevant measurement conditions such that the reader can understand not only what the data is but also how the data was collected could repeat the measurement, if so desired. The first sentence canbe a sentence fragment but doesn’t have to be.1: https://pubs.acs.org/doi/full/10.1021/acsguide.40303Example of a Figure Caption: “Reaction yield as a function of added catalyst with reaction yield determined by absorption measurements. Reactions were held at a constant temperature of 22±2/°C. Concentrations of all other reactants were kept constant at the values shown in Table/9. Each data point is the average of three trials.”-NOTE TO STUDENTS: Don’t feel the need to include things just to make the caption longer. As a start, aim for something similar to the first sentence of the figure caption example (what is being displayed in the figure) and include one other sentence that plainly states a relevant measurement condition (e.g., the temperature of the solution was allowed to equilibrate for 5 min. before recording each measurement.) If other (obviously important) measurement conditions are identified, those can be included but the main goal here is learning what to include in the caption, not making a lengthy caption.Also, in the example figure caption above, the end of the first sentence states, “…with reaction yield determined by absorption measurements”. The general idea is to state what experimental technique was used to determine the dependent variable values, which was “reaction yield” in this example. This information is needed in a figure caption for experimental data.1CHEM 101L Post-Lab Assignment: Experiment 1 Spring 2022Note on Table Titles: The ACS states that each table must include a one phrase (or sentence) title that describes the contents of the table. The title should be understandable without reference to the text or, in this case, the lab manual.1Example of a Table Title: “Rate constants for substitution reaction A as a function of temperature.”Note on Units for Table Entries: For each entry in a table, units should be included, either in the column header or in a separate column (similar to how units are treated in Excel), unless thequantity is actually unitless. The ACS does not require a separate column for units in a table but is requested here to avoid confusion.Note on Description of Data: In addition to tables and figures, the Results
