FormulaWeight

Science is an important part of existence, but with the abundance of discoveries adding up to the already stunning amount of info, it can be difficult to learn, and track everything. In this regard, FormulaWeight comes as a lightweight app with which to instantly calculate the weight of molecular structures, based on different values.

Lightweight, and easy to use

It’s best to check whether or not .NET Framework is installed on your computer before you go checking the application’s set of features. If it is, the main window shows up before you realize, with setup only lasting a little while.
The main window is pretty intuitive, and since you’re looking for chemistry tools, you instantly recognize the design, which enlists all known elements in Mendeleev’s Table. A numerical tab is also at your disposal in order to specify neutron number of each element you select, as well as the result field.

Result automatically copied to clipboard

All your effort narrows down to selecting the elements you want to sum up. The results field lets you add a decent amount of values, but you need to know what you’re doing, otherwise the result returns in error. Formula weight is calculated as you select values, and is automatically copied to the clipboard so you can insert it with little effort where needed.
By default, the application assigns the value 1 for each element you select. Changing it needs to be done right after selecting an element, otherwise you can’t come back to edit any existing values. What’s more, there’s no history tracker in case unexpected events occur, to check whether or not you picked the right elements.

To sum it up

All things considered, we can safely state that FormulaWeight is sure to skip you a great deal of effort, and reduce the risk of error when calculating weight for different chemical formulas. However, you still need to pay attention every step of the way because of the ambiguous edit process, while result history isn’t saved, so you need to do so for every value of interest.
