How many liter of pure hydrochloric acid must be added to 60 liters of solution
\n" ); document.write( "that is 10% hydrochloric acid to get a solution that is 15% hydrochloric acid?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of pure acid required
\n" ); document.write( ":
\n" ); document.write( ".10(60) + x = .15(x+60)
\n" ); document.write( ":
\n" ); document.write( "6 + x = .15x + 9
\n" ); document.write( "x - .15x = 9 - 6
\n" ); document.write( ".85x = 3
\n" ); document.write( "x = \"3%2F.85\"
\n" ); document.write( "x ~ 3.53 liters of pure acid
\n" ); document.write( "
\n" );
