Free Chemistry Assistant is a handy free calculator for rapid computation of molecular mass of chemical compounds. Enter chemical symbols manually or select from an abbreviated drop-down list to enter the formula of the compound, then let the program calculate molecular weight based on your input. A translation display shows the grouping of elements and numbers of molecules that the program is considering, even if you enter data in all-lowercase letters. Chemistry Assistant also contains a comprehensive list of physical constants, prefixes, and SI units, plus a custom constant list for you to develop with your own frequently used items. The interface also includes a full-featured calculator with both scientific and general notation.
Detailed help explains all the controls and functions.
