Study Set Content:
Normality symbol
N
Unit of Normality
equivalent/L
Formula of Normality
Normality = Number of grams – Equivalent of solute / Volume of solution in L
Number of gram-equivalents of solute = Mass of solute in gram / Equivalent weight
Number of gram-equivalents of solute = Mass of solute in gram / Equivalent weight
Milliequivalents Symbol
mEq
Represents amount in milligram of a solute equal to 1/1000 of its gram equivalent weight taking into account the valence of the ions.
Milliequivalents
Formula :mEq
mg x valence atomic/ molecular or formula weight
Osmolarity Symbol :
mOsmol/L
Formula : Osmolarity
mOsmol/L = wt of substance (g/L) x number of species x 1000/MW (g)
