You can put this solution on YOUR website!
(Amount of salicylic acid)/(amount of solution)=concentration of salicylic acid\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let v = volume of salicylic acid to use.
\n" ); document.write( "Let r = volume of the alcohol to use.
\n" ); document.write( "volumes are in milliliters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"17%2Av%2F%28v%2Br%29=2\" and \"v%2Br=473\"
\n" ); document.write( "Solve for v and r.
