HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS (Perchloric Acid 60.0 %w/w) AND FORMULA TO MEASURE THEM

HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS
(Perchloric Acid 60.0 %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 Perchloric Acid 60.0 %w/w
Following Values are Required of concentrated solutions  :
Molecular Formula                       = HClO4
Molecular Weight                         = 100.46
Assay or Purity of Compound     = 60.0%w/w
Weight per ml of compound        = 1.54

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 1.54 x  60.0
                                            100.46 x 100
                               = 9.198 M
Concentrated Perchloric Acid 60.0 %w/w is about 9.198 M
9.198 M                = 1000 ml Conc. Perchloric Acid 60.0 %w/w
For 1M                  = 1000 ml Conc. Perchloric Acid 60.0 %w/w
                                                     9.198
                               = 108.72 ml Perchloric Acid 60.0 %w/w Required

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...
