1. Graphical Analysis
a. Calculate the atomic volume for each element using the equation V = (4/3)pr3. Place the numbers in the appropriate column or, use excel to generate the numbers.
b. As 3 separate graphs, plot density as a function of (graph 1) atomic radii; (graph 2) atomic mass; (graph 3) atomic volume. Print out or submit the graphs with the table of data and questions.
Table of Given Data
Atomic Radii (Å)
Atomic Mass (AMU)
Atomic Volume (Å3)
2. Data Interpretation.
a. Using the 3 graphs, which parameter (radii, mass or volume) correlates to the density of the metal? How did you make this determination?
Mass because the density is the
b. A student plans to measure the volume of a reagent using a transfer pipet with a volume of 10.00 ± 0.02 ml.
i. What is the range of volume the student can expect to deliver if she uses the pipet properly?
ii. If the student needs to measure a volume 20.0 ml, what should the student do
b. i.10.00 ± 0.02 ml.
