How many kilograns of water must be evaporated from 50 kg of a 10% salt solution to obtain a 15% salt solution?
\n" ); document.write( ".
\n" ); document.write( "Let x= amount (kilograms) of water evaporated
\n" ); document.write( "then
\n" ); document.write( ".10(50) = .15(50-x)
\n" ); document.write( "5 = 7.5 - .15x
\n" ); document.write( "-2.5 = -.15x
\n" ); document.write( "2.5 = .15x
\n" ); document.write( "2.5/.15 = x
\n" ); document.write( "250/15 = x
\n" ); document.write( "50/3 = x
\n" ); document.write( "16.67 kilograms = x
\n" ); document.write( " \n" ); document.write( "
