You can put this solution on YOUR website!
Assuming percents to be mass per mass, then you need these:
\n" ); document.write( "

\r\n" );
document.write( "85% ----------- 1.689 grams/ml density\r\n" );
document.write( "15% ----------- 1.0824 grams/ml density\r\n" );
document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "w, mass of water to add\r
\n" ); document.write( "\n" ); document.write( " $\"%281000%2A1.689%2A85%29%2F%28w%2B1000%2A1.689%29=15\"$
\n" ); document.write( "Solve this to get the MASS of water to use, in grams... and then you can convert into its volume if you wish...\r
