You can put this solution on YOUR website!
(salt)/(salt solution)=0.40\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The salt material is 100% salt. The current solution is the lower concentration material at 28% or 0.28. You have 40 grams of this solution and you do not need to know how much resulting solution quantity.\r
\n" ); document.write( "\n" ); document.write( "m= grams of salt solid to add,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28m%2A1.00%2B40%2A0.28%29%2F%28m%2B40%29=0.40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for m.
