How much water must be evaporated from a 20 liter 32% salt solution if the desired concentration is 50%?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of water to be evaporated
\n" ); document.write( ":
\n" ); document.write( "The actual amt of salt will be the same
\n" ); document.write( ".32(20) = .50(20-x)
\n" ); document.write( "6.4 = 10 - .5x
\n" ); document.write( ".5x = 10 - 6.4
\n" ); document.write( "x = 3.6/.5
\n" ); document.write( "x = 7.2 liters of water to be evaporated
\n" ); document.write( "
\n" );
