Stoichiometry
Stoichiometry
is the study and calculation of
quantitative (i.e. measurable) relationships
between the reactants and products in
chemical reactions (chemical equations).
The word is derived from the Greek word
stoikheion ("element") and metri
ā
("measure," from metron). Stoichiometry is
concerned with numerical relationships of
chemical formulas and chemical equations
Stoichiometric Calculations
1.
Write and balance your chemical equation;
2.
Calculate molar masses of any materials for
which have been given amounts OR will
have determine amounts for;
3.
Convert any masses given to moles;
4.
Use balanced equation to determine
stoichiometric ratios needed;
5.
Calculate moles of desired materials;
6.
Calculate grams of desired materials.
