It is the measure of the quantitative relationship between the products and
reactants of a given chemical reaction in terms of their relative ratios of
mass or volume.
Stoichiometry
It refers to the relationship between the quantities of reactants and products
before, during, and following chemical reactions.
Stoichiometry
It is founded on the law of conservation of mass where the total
mass of the reactants equals the total mass of the products, leading to the
insight that the relations among quantities of reactants and products typically
form a ratio of positive integers.
Stoichiometry
Stoichiometry tells us what quantity of each ____ we need in order
to get enough of our desired product. Because of its real-life
applications in chemical engineering as well as research, ____ is one of the most important and fundamental topics in chemistry

Composition stoichiometry
Reaction stoichiometry
It is the field of chemistry that is concerned with the
relative quantities of reactants and products in chemical reactions. For any
balanced chemical reaction, whole numbers (coefficients) are used to show
the quantities (generally in moles ) of both the reactants and products.
Reaction stoichiometry
It refers to the atomic makeup of a molecule.
For instance, we can say that one molecule of glucose has 6 carbon atoms, or
we can say, equivalently, that one mole of glucose has 6 moles of carbon
atoms.

Also spelled mol, in chemistry, a standard scientific unit for
measuring large quantities of very small entities such as atoms,
molecules, or other specified particles. Designates an
extremely large number of units, 6.02214076 × 10^23
MOLES
is the base unit of amount of substance in the International System of Units. It is defined as exactly 6.02214076×10^23 elementary entities, which may be _____, _________, ____, or _________.
Moles
atoms, molecules, ions, or electrons
It is a property that reflects the quantity of matter within a sample. It usually is reported in grams (g) and kilograms (kg). It may also be considered to be the property of matter that gives it a tendency to resist acceleration. The more of this an object has, the harder it is to accelerate it.
Mass
It is the quantity of matter in a physical body. It is also a measure of the body’s inertia, the resistance to acceleration when a net force is applied. An object’s ____ also determines the strength of its gravitational attraction to other bodies.
Mass
The SI base unit of mass is the
Kilogram
It is the amount of 3D space a substance or object occupies. It is a derived unit, depending on 3 quantities: ______, _____, and ______. Therefore, though the beakers each contain the same ______, their differing lengths, widths, and heights makes that ______ look deceptively different.
Volume
length, width, and height
