how much water must be evaporated from 36 ounces of a 5% salt solution to make a 9% salt solution\r
\n" ); document.write( "\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "let x=ounces of water that must be evaporated.
\n" ); document.write( "36-x =ounces of water remaining.\r
\n" ); document.write( "\n" ); document.write( "Initially, you had 5% solution in 36 ounces of water.
\n" ); document.write( "The amount of salt in the solution did not change, it remained the same. You just reduced the amount of water to get a higher concentration of salt.\r
\n" ); document.write( "\n" ); document.write( ".05(36)=.09(36-x)
\n" ); document.write( "1.8=3.24-.09x
\n" ); document.write( ".09x=3.24-1.8=1.44
\n" ); document.write( "x=1.44/.09=16
\n" ); document.write( "ans:
\n" ); document.write( "16 ounces of water must be evaporated from 36 ounces of a 5% salt solution to make a 9% salt solution\r
