HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS (Red Fuming Nitric Acid) AND FORMULA TO MEASURE THEM

HOW MUCH MOLARITY OF STANDARD CONCENTRATED ACIDS 
(Red Fuming Nitric Acid)
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 Conc. Red Fuming Nitric Acid
Following Values are Required of concentrated solutions  :
Molecular Formula                       = HNO3
Molecular Weight                         = 63.01
Assay or Purity of Compound     = 90.0%w/w
Weight per ml of compound        = 1.50

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 1.50 x  90.0
                                            63.01 x 100
                               = 21.43 M
Concentrated Red Fuming Nitric Acid is about 21.43M
21.43M                 = 1000 ml Conc.Red Fuming Nitric Acid
For 1M                  = 1000 ml Conc.Red Fuming Nitric Acid
                                                     21.43
                               = 46.66 ml Conc. Red Fuming Nitric Acid Required
