Use 42% acid and 18% acid solutions to make 32 mL. of 30%.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If v mL. of 42%, then to account for pure acid,
\n" ); document.write( "\"42v%2B18%2832-v%29=30%2A32\"
\n" ); document.write( "and solve for v.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Be aware that \"%2842%2B18%29%2F2=30\", so the student will need 16 mL. of each of the starting solutions of acid.
\n" ); document.write( "
\n" );
