Achemist has two solutions of h2so he has one 40% concentration the other has 25% concentration how many liters of each solution must be mixed to obtain 96 l of a 37% solution

                         Qty                  %                  = Qty (%)

Solution 1:          x                   .40                  .40(x)    

Solution 2:      96 - x             .25                 .25(96 - x)  

   Mixture:       96                  .37              .40x + .25(96 - x)

                                         96(.37)      =    .40x + .25(96 - x)

                                           35.52     =    .40x +   24 - .25x

                                           35.52     =    .15x +   24

                                            11.52     =    .15x

                                             76.8     =     x

Solution 2: 96 - x  = 96 - 76.8   = 19.2

76.8 L of 40% solution, 19.2 L of 25% solution
