Molecular Weight Calculator

Molecular Weight Calculator is an add-in that was designed for Microsoft Excel users that need to calculate the molecular weight of various substances directly from the host application. This add-in actually implements a function that, upon calling it, is capable of returning precise values regarding the molecular weights of certain chemicals.

Its calculations are based on a single string argument that can be called anywhere in the spreadsheets so that it can return the desired results. Users only need to include the chemical formula or make a cell reference that contains the chemical formula. For example, if the users need to determine the molecular weight of water, it is sufficient to type "=MW("H2O")." Molecular Weight Calculator automatically detects the formula and retrieves the result.

It is worth mentioning that the elements are case sensitive. Users need to type their symbols exactly as they appear in Mendeleev's Periodic Table of Elements. For instance, iron will be typed as "Fe" instead of "FE" or "fe," so that the add-in can recognize and use it accordingly.

Users can also use the add-in to create projects such as mole percent to weight percentage calculators for various types of substances, according to their needs.
