You can put this solution on YOUR website!
You need the densities.
\n" ); document.write( "Percent Weight_______density g/ml
\n" ); document.write( "8____________________1.0376
\n" ); document.write( "12.2_________________est. 1.059
\n" ); document.write( "15___________________1.0723\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(referenced http://www.handymath.com/cgi-bin/hcltble3.cgi?submit=Entry ).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equations rely on being strictly in percents weight per weight.\r
\n" ); document.write( "\n" ); document.write( "Let u = VOLUME of 8% acid
\n" ); document.write( "Let v = volume of 15% acid\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28u%2A8%2A1.0376%2Bv%2A15%2A1.0723%29%2F%28100%2A1.059%29=12.2\"$ , accounts for the percent concentration;
\n" ); document.write( "and
\n" ); document.write( " $\"u%2Bv=100\"$ should account well for the volumes.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Those two equations as a system will really be found to be two linear equations in variables u and v. \n" ); document.write( "

\n" );
