Hi! I need a calculator to do the following. For example: 1 bottle of liquid foundation (no added flavors, only PG + GV) of 0 mg / ml to 200 ml. Another liquid pot high nicotine base for example to 36 mg / ml nicotine 200ml. And the calculator tells me how many milliliters of 0 mg I have to dump into the pot 20ml and how many milliliters of 36 mg I have to dump into the pot 20 ml for total 1 bottle of 20 ml x mg / ml nicotine . Have I explained ok? Thank you very much!
