Algebra.Com's Answer #423783 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Determine how many liters of 6% acid solution and how many liters of 12% acid solution should be mixed by a chemist to obtain 6 liters of 10% acid solution. \n" ); document.write( ": \n" ); document.write( "Let x = amt of 12% solution \n" ); document.write( "the resulting amt is to be 6 liters, therefore: \n" ); document.write( "(6-x) = amt of 6% solution \n" ); document.write( ": \n" ); document.write( "A typical mixture equation, using the the decimal equiv of per cent \n" ); document.write( ".12x + .06(6-x) = .10(6) \n" ); document.write( ".12x + .36 - .06x = .6 \n" ); document.write( ".12x - .06x = .6 - .36 \n" ); document.write( ".06x = .24 \n" ); document.write( "x = .24/.06 \n" ); document.write( "x = 4 liters of the 12% solution \n" ); document.write( "and \n" ); document.write( "6 - 4 = 2 liters of 6% solution \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Confirm this solution \n" ); document.write( ".12(4) + .06(2) = .10(6) \n" ); document.write( ".48 + .12 = .6; \n" ); document.write( "I don't know how they got a solution of 3.6 from this; anyway I wish you and your family a Happy Thanksgiving!!! \n" ); document.write( " |
