Normality is "equivalents per liter". Take the molarity and multiply by the number of equivalents per mole. That gives equivalents per mole. The number of equivalents per mole is usually the number of protons or hydroxide ions a chemical can donate. For example, sulfuric acid [H2SO4] has 2 equivalents per mole.

add the molecular weights of the components of the compounds, divide by number of hydrogen atoms present in the compound
eg: NaOH
Na=23
O=16
H=1
23+16+1=40
number of hydrogen atoms=1
40/1=40
hence, normality of NaOH=40

Normality for non acids and bases requires that you know the reaction for which the solution will be used.
Molarity is moles / liters
