HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS (Ammonia 25.0 %w/w )AND FORMULA TO MEASURE THEM

HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS
(Ammonia 25.0 %w/w )AND FORMULA  TO MEASURE THEM
Following Values are Required of concentrated solutions  :
Molecular Formula
Molecular Weight
Assay or Purity of Acid
Weight per ml of Acid

Formula:-                 1000ml x Wt.per ml x Purity of Conc. Solution
                                                    Molecular weight x 100
                                   = ? M

Example :- For Ammonia 25.0 %w/w
Following Values are Required of concentrated solutions  :
Molecular Formula                       = NH3
Molecular Weight                         = 17.031
Assay or Purity of Compound     = 25.0%w/w
Weight per ml of compound        = 0.91

Put the given values in following formula
Formula:-                 1000ml x Wt.per ml x Purity of Conc. Solution
                                                    Molecular weight x 100
                               = ? M
                               =    1000ml x 0.91 x  25.0
                                            17.031 x 100
                               = 13.358 M
Concentrated Ammonia  25.0 %w/w is about 13.358 M
13.358 M              = 1000 ml Ammonia 25.0 %w/w
For 1M                  = 1000 ml Ammonia 25.0 %w/w
                                                     13.358
                               = 74.86 ml Ammonia 25.0 %w/w Required

WHAT IS GSM AND HOW TO CALCULATE

          WHAT IS GSM AND HOW TO CALCULATE GSM MEANS GSM  is an acronym standing for 'Grams per Square Meter'. Quite simply, it allows buyers and   suppliers to know exactly about the quality of  paper or foil that is being ordered. AND HOW TO CALCULATE GSM OF PAPER AND FOIL IT’S VERY SIMPLE, FIRST WE CUT OF RECTANGULAR PIECE OF PAPER AND FOIL IN ANY SIZE ACCORDING TO YOUR CHOICE . MEASURE THE DIMENSIONS OF RECTANGULAR PIECE IN MILIMETER (mm) OR CENTIMETER(cm) SUPPOSE THE DIMENSIONS OF RECTANGULAR PIECE IN CENTIMETER (cm) ONE METER IS EQUIVALENT TO 100cm ONE SQUARE METER = 1meter x1meter                                       = 100cm x 100cm                 ...

Difference Between μg ,mcg or ppm

Difference Between μg  ,mcg or ppm All are same, why we can say all are same Tri to understand as following μg    =   one millionth ( 1×10 −6 ) of a   gram ,        = one gram/1000000 = 0.000001g or 0.001mg mcg =   one millionth ( 1×10 −6 ) of a   gram        = one gram/1000000 = 0.000001g or 0.001mg ppm =   ppm   (parts-per-million)            one millionth ( 1×10 −6 ) of a   gram .         =one gram/1000000 = 0.000001g. or 0.001mg So, we can say that the μg  ,mcg or ppm are same. For example : We want to make 100ml of 10 μg/ml dilution.            = 10 x 0.000001g( μg )= 0.00001g/ml or 0.01mg/ml.               For 100ml = 0.01mg x 100ml or...

METHOD OF ANALYSIS OF TOLNAFTATE

METHOD OF ANALYSIS OF TOLNAFTATE Weight accurately about 0.4 g of Tolnaftate, dissolve in 50 ml of anhydrous glacial acetic acid . Previously neutralized with 0.1 M Perchloric acid . Using Crystal Violet as indicator and add 20 ml mercuric acetate solution ( Previously neutralized with 0.1 M Perchloric acid . Using Crystal Violet as indicator) Titrate with 0.1 M Perchloric acid upto green colour changed. Each ml of 0.1 M Perchloric acid is equivalent to 0.030741g of Tolnaftate .
