Algebra.Com's Answer #584189 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! A chemist has two solutions. One is 40% alcohol, and the other is pure alcohol. How much of each solution should be mixed together to make 1.6 liters of a solution that is 52% alcohol? \n" ); document.write( "*** \n" ); document.write( "let x=amt of 40% alcohol to mix \n" ); document.write( "1.6-x=amt of pure(100%) alcohol to mix \n" ); document.write( ".. \n" ); document.write( "40%x+100%(1.6-x)=52%*1.6 \n" ); document.write( ".40x+1.6-x=0.832 \n" ); document.write( ".60x=0.768 \n" ); document.write( "x=1.28 \n" ); document.write( "1.6-x=0.32 \n" ); document.write( "amt of 40% alcohol to mix=1.28 liters \n" ); document.write( "amt of pure(100%) alcohol to mix=0.32 liters \n" ); document.write( "note: your setup is ok, you just added instead of subtracting in the 4th step. \n" ); document.write( " |
