Question

10.0 volune 11. Which measurement, mass or volume, contributes the most to the uncertainty of the final answer and should, therefore, be used to set the standard for comparison for this experiment? 12. Complete the following R&D paragraph based on the results for aluminum. Make sure to include units when needed. NOTE: For this first semester of laboratory, the results and discussions are presented as fill-in-the-blank models for you to complete. These models follow the guidelines for technical writing presented in the introductory material of the lab manual. Pay close attention this semester to the format, language choices, phrasing choices, and order of presentation. In General Chemistry 2 laboratory, you will be expected to create your own R&D paragraphs following the guidelines. 45mL A%error of The average density of aluminurm was compared to the literature value of . was obtained showing good, marginal, or poor based on the tolerance indicated by the uncertainty accuracy or precision of the measurements. A correlation coefficient of was obtained mass or volume for the linear regression showing good, marginal, or poor accuracy or precision based on the value of expected for quantities that are directly related.

Explanation / Answer

The average density of Aluminium was kg/m3.The percentage error of average density was obtained compared to the literature value of results showing good accuracy based on the percentage tolerance indicated by the uncertainity of the volume measurements. A correlation coefficient of experiment was obtained of the linear regression showing good accuracy based on the value results expected for the quantities that are directly related.
