Single Compound Stoichiometry
Single Compound Stoichiometry
"Single compound stoichiometry" refers to calculations used to determine AMOUNTS of single compound materials in chemistry. Formula weight and Mole-Atom-Gram (MAG) conversion calculations as especially essential in moving forward with chemical reactions!
Formula Weight and % Composition
Formula weight and % composition are ways to describe the "size" of the compound. Formula weight would be similar to human weight while % composition would be analogous to knowing how much a person's arms or legs weigh within the total body weight.

Skeptical Questions In Science
Skeptical Questions In Science
The skeptical question topic for this unit involves the topic of "food additives". Skeptical questions are thoughtful "Why-based" questions which address biases in scientific material. This type of question is not seeking scientific facts.

MOLES
MOLES
A key concept to understand in chemistry is the "mole". In stoichiometry, and later on in chemical reactions, moles are an AMOUNT, but they are also a method of CONVERSION. The two key mole conversions are:
1 mole = (FW)g of any substance
1 mole = (FW)g of any substance
1 mole = 6.02 x 10^23 of anything (usually atoms, units, or molecules)
1 mole = 6.02 x 10^23 of anything (usually atoms, units, or molecules)
Mole-Atom-Gram Conversions
MAG conversions are a set of chemistry conversions used to move among the three main measurement systems:
Lab Measurement (GRAMS)
Unit Counting (ATOMS)
Calculations (MOLES)
MAGProb21.pdfMAGAnswers21.pdfMolarity and Molar Recipes
"Molarity" in chemistry refers to how concentrated a substance is. Molar recipes allow us to make substances of a specific concentration. The following terms are used with molarity:
1M = "normal"
1M = "normal"
>1M = "concentrated"
>1M = "concentrated"
<1M = "dilute"
<1M = "dilute"
MolProb21.pdfMolAnswers21.pdfEmpirical Formulas
Empirical formula determination is actually a lab procedure in chemistry. This process is used to determine the formula of an unknown substance in the lab setting.
EmpFormProb21.pdfEmpFormAnswers21.pdfEmpirical Formula Full Lab
The purpose of this lab is to use the empirical formula process to determine the chemical formula of an unknown material in lab. This lab is a modification of a college chemistry lab, so the procedural part requires students to determine experimental steps from the actual college lab document.
