You can put this solution on YOUR website!
20 ounces of 8% salt solution yields 1.6 ounces of salt and 18.4 ounces of water.
\n" ); document.write( "if you want 1.6 ounces of salt to be 2% of a solution, then you divide 1.6 by .02 to get 80 ounces of solution. 1.6 / 80 equates to .02 so this new solution is 1.6 ounces of salt and 78.4 ounces of water.
\n" ); document.write( "since you already have 18.4 ounces of water in the original solution, you need to add (78.4-18.4) = 60 ounces of water.
\n" ); document.write( "you take your original solution of 20 ounces and add 60 ounces of water.
\n" ); document.write( "the original solution had 1.6 ounces of salt and 18.4 ounces of water to make a total of 20 ounces of solution.
\n" ); document.write( "the new solution has 1.6 ounces of salt and 78.4 ounces of water to make a total of 80 ounces of solution.
\n" ); document.write( "1.6 / 20 = .08
\n" ); document.write( "1.6 / 80 = .02\r
