Stoichiometric Calculations
Terms
Conversion Factor
-
A ratio (or fraction) that represents the relationship between two different
units.
Formula Unit
-
The representative particle of a substance. It is the smallest unit of a
substance that still retains that substance's properties and is the simplest way
to write the formula of the substance without coefficients.
Gram Formula Mass
-
The mass of one mole of compound.
Gram Molecular Mass
-
The mass of one mole of a molecular substance.
Mole
-
A measure of amount. 1 mole equals
6.02×1023
items of something.
The number is so massive because moles are used to measure the amount of
molecules, atoms, and other incredibly miniscule particles.
Mole ratio
-
The ratio between any two constituents in chemical equation
Standard Temperature and Pressure
-
The arbitrarily decided standard conditions at which experiments are done: 1 atm
and 273 degrees Kelvin (0 degrees Celsius).
