What This Document Is
This document is the answer key for the first homework assignment in GLY 4200C, Mineralogy & Crystal Chemistry at Florida Atlantic University. It focuses on applying formulas to calculate density and specific gravity of minerals, utilizing concepts related to unit cells, molecular weights, and Avogadro’s number. It was created for Fall 2012.
Why This Document Matters
This key is essential for students enrolled in GLY 4200C who have completed Homework Exercise 1. It allows students to check their work and understand the correct application of the formulas presented in the course. It’s used after attempting the problems to reinforce learning and identify areas needing further review.
Common Limitations or Challenges
This document provides *answers* to specific problems, but it does not offer detailed explanations of the underlying mineralogical principles. It assumes students have already been introduced to the concepts of density, specific gravity, unit cells, and molecular weight. It will not teach the core concepts; it only validates application of those concepts.
What This Document Provides
The full document includes:
* Worked solutions for five problems related to calculating density and specific gravity.
* Formulas for calculating density from mineral data, including definitions of variables (Z, M, N, V).
* Conversion factors between Angstroms/nanometers and centimeters.
* Calculations for specific minerals including nantokite, salesite, samuelsonite, monazite, and erythrite.
* Answers expressed in both grams per cubic centimeter and kilograms per cubic meter.
This preview does *not* include the full step-by-step calculations or explanations of the concepts. It only provides a high-level overview of the document’s contents.
