Hopefully this is of use to some, get it while it's available.. And I have not personally used this prior to ten minutes ago (installed and tested links and softwares functionality prior to posting links)..

This program will calculate & instruct you in how to prepare: Molar solutions, by using built in atomic weights. Percentage solutions from stock solutions. Anhydrous solutions. You can print out the instructions for your desired solution, as well as a label to fix to your preparation. You will find the program extremely simple to use with minimal training required.

My Norton antivirus says that one of the keygen files is a trojan (crack.exe). Otherwise the true keygen program (inside the 2nd zip) works and does not seam to be infected.
Also I found the “EniG. Chemistry Assistant” much, much better for similar purposes and it also contains a loot of useful chemical data and a calculator: Post 481689 (https://www.thevespiary.org/talk/index.php?topic=7092.msg48168900#msg48168900)
(wareami: "Calculating moles software", Chemistry Discourse). Unless there is something I did not understood, the above program (that can’t even parse chemical formula by itself) is not worth installing.
