“Solution Calculator” is a convenient calculator for making chemical solutions and for diluting solutions using a stock solution. It helps you to quickly determine how much chemical/stock solution you need. It is useful for students taking chemistry classes, or researchers working in a biology, chemistry or biochemistry laboratory. You do not need to mess around with your calculator and can spend more time in your study or research.Solution Calculator also contains a handy tool to calculate molecular weight (M.W.) of commonly used chemicals in the lab. You do not need to enter the name or molecular formula of the chemical, you just need to press a few buttons to get the MW of the chemical instantaneously.
