Hi chemists (especially people doing synthesis),
let me introduce a calculator.
Since 2006, I started to make it as a chemist for easier life working in the lab.
For a long time I and my colleagues have used and tested the calculator. We think it works fine.
The calculator is web-based one, so you can use it wherever you can access internet.
Some browsers (i.e. seamonkey) it doesn't work perfectly.
I hope the calculator is useful for you, and your feed-back is always welcome.
Please use links below and find instruction on the help page.
