You can put this solution on YOUR website!
If you mean, LITERS, then use an abbreviation that cannot be misunderstood, like either L or the word, \"liters\".\r

\n" ); document.write( "\n" ); document.write( "Make a formula to use starting if possible, with all symbols, because you will compute twice - you want a range of values for how much of the 30% acid to use.\r

\n" ); document.write( "\n" ); document.write( "T, the target resulting value from 15% to 18% acid
