A mixture containing 6% boric acid is to be mixed with 4 liters of a mixture which is 25% boric acid in order to obtain a solution which is 12% boric acid. How much of the 6% solution must be used?
\n" ); document.write( "---------------------------------
\n" ); document.write( "Acid EQUATIOn: 0.06x + 0.25*4 = 0.12(x+4)
\n" ); document.write( "6x + 100 = 12x + 48
\n" ); document.write( "6x = 52
\n" ); document.write( "x = 8 2/3 liters (amt. of 6% solution that must be added)
\n" ); document.write( "===============
