Molarity. Molarity is the number of moles of solute dissolved in one liter of solution
molarity =no of moles of solute / volume of solution per littre
Normality is similar to molarity, but uses equivalents, not moles of the substance. It is expressed as number of equivalents per liter. Thus the same solution can have different normalities for different types of reaction
normality=no of gram equivlent (equivlent weight) / volume of solution per littre
the realtion between both of them is
N * equivlant weight = M* Molecular weight
it is drieved from
since wt=(N*v*eq) / 1000
and wt=(m*v*M.wt) / 1000
from the above 2 equations we get know that
N*eq=M*M.wt
where N=refer to normality
eq=refer to equivlant weight
M=refer to molarity
M.wt=refer to molecular weight

Molarity is the number of moles of solute per litre of solution. (Well, I presume you meant 'molarity' and not 'morality' !)
For example, a solution containing 0·8g of sodium hydroxide per litre will have a molarity of 0·8 ÷ 40 , which equals 0·2 , 40 being the molar mass of NaOH.
This is usually written 0·2M or 0·2 molar.
The normality is the molarity multiplied by a factor that depends on the reaction involved. This factor is always a whole number and is equal to the number of protons transferred or the change in oxidation number (i.e. the number of electrons transferred).
For the neutralisation of a diprotic acid, such as sulphuric acid, or a diprotic base, such as barium hydroxide, the factor will be 2, i.e. the normality will be double the molarity.
It can happen that two different factors apply to the same substance. For instance, with oxalic acid, if it is used in an acid-base neutralisation, the factor is 2 (since oxalic acid is diprotic), but if it is used in a redox reaction, the factor is 1, since the change in oxidation number is 1.

Normality is:
In Psychology
a. approximately average in any psychological trait, as intelligence, personality, or emotional adjustment.
b. free from any mental disorder; sane.
Biology,
Medicine/Medical. a. free from any infection or other form of disease or malformation, or from experimental therapy or manipulation.
b. of natural occurrence
Mathematics.
a. being at right angles, as a line; perpendicular.
b. of the nature of or pertaining to a mathematical normal.
c. (of an orthogonal system of real functions) defined so that the integral of the square of the absolute value of any function is 1.
d. (of a topological space) having the property that corresponding to every pair of disjoint closed sets are two disjoint open sets, each containing one of the closed sets.
e. (of a subgroup) having the property that the same set of elements results when all the elements of the subgroup are operated on consistently on the left and consistently on the right by any element of the group; invariant.
a. a perpendicular line or plane, esp. one perpendicular to a tangent line of a curve, or a tangent plane of a surface, at the point of contact.
b. the portion of this perpendicular line included between its point of contact with the curve and the x-axis.
Chemistry. a. (of a solution) containing one equivalent weight of the constituent in question in one liter of solution.
b. pertaining to an aliphatic hydrocarbon having a straight unbranched carbon chain, each carbon atom of which is joined to no more than two other carbon atoms.
c. of or pertaining to a neutral salt in which any replaceable hydroxyl groups or hydrogen atoms have been replaced by other groups or atoms, as sodium sulfate, Na2SO4.
Morality in its defined terms are:
1. conformity to the rules of right conduct; moral or virtuous conduct.
2. moral quality or character.
3. virtue in sexual matters; chastity.
4. a doctrine or system of morals.
5. moral instruction; a moral lesson, precept, discourse, or utterance.
The quality of being in accord with standards of right or good conduct.
A system of ideas of right and wrong conduct: religious morality; Christian morality.
Virtuous conduct.
A rule or lesson in moral conduct
1. concern with the distinction between good and evil or right and wrong; right or good conduct [ant: immorality]
2. motivation based on ideas of right and wrong [syn: ethical motive]
The equation between the two are motivation based on ideas of right and wrong and morally objectionable behavior

first i suppose that the second term is MOLARITY
If you have a solution containing x grams of solute by liter
the molarity is equal to x/molecular weight of the solute
Normality if a solute has a valence v
the normality is the molarity multiplied by v

Normality is what happens normally and morality is clean and acceptable behavior.
