Making Chemicals and Solutions

If you work out the math once, save it on an index card so it is easy to use at the scale or at your research bench. It’s likely you’ll make the reagent, solution, or medium again.

Also, use an app or calculator to get the math right the first time. The most expensive chemical in the lab is the one that is made up wrong, and everyone uses. It's always worth your time to double-check.
