A pot contains 2 L of brine at a concentration of 100 g/L.
\n" ); document.write( " How much of the water should be boiled off to increase the concentration to 200 g/L?
\n" ); document.write( ":
\n" ); document.write( "Convert 100g/L to 10% brine, which is .10
\n" ); document.write( ".10(2) = .20(2-w)
\n" ); document.write( ".2 = .4 - .2w
\n" ); document.write( ".2w = .4 - .2
\n" ); document.write( ".2w = .2
\n" ); document.write( "w = 1 liter should be boiled off
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this
\n" ); document.write( ".10(2) = .20(2 - 1)
\n" ); document.write( ".2 = .2(1) \n" ); document.write( "
\n" );
