mass
: The amount of matter in an object. The more mass, the more stuff is 
present.
•
mechanism
: A step-by-step sequence that shows how the products of a 
reaction are made from the reagents. Mechanisms are very frequently shown 
during organic chemistry.
•
molality
: The number of moles of solute per kilogram of solvent in a solution.
This is a unit of concentration that's not anywhere near as handy or common 
as molarity.
•
molar mass
: The mass of one mole of particles. 
•
molar volume
: The volume of one mole of a substance at STP. If you 
believe that everything is an ideal gas, this is always 22.4 liters. Unfortunately, 
there's no such thing as an ideal gas.
•
molarity
: A unit of concentration equal to moles of solute divided by liters of 
solution.

•
mole fraction
: The number of moles of stuff in a mixture that are due to one 
of the compounds. 
•
mole ratio
: The ratio of moles of what you've been given in a reaction to what 
you want to find. Handy in stoichiometry.
•
mole
: 6.02 x 10
23
things.
•
molecular compound
: A compound held together by covalent bonds.
•
molecular formula
: A formula that shows the correct quantity of all of the 
atoms in a molecule.
•
monatomic ion
: An ion that has only one atom, like the chloride ion.
•
neutralization reaction
: The reaction of an acid with a base to form water 
and a salt.
•
node
: A location in an orbital where there's no probability of finding an 
electron.
•
nonpolar covalent bond
: A covalent bond where the electrons are shared 
equally between the two atoms.
