The Mole Calculator app provides users with the best and easiest tool around to find the molar mass of various compounds. This calculator will take a compound's formula as it's input, and will output that formulas molar mass.

You can also input grams if you like, and it will tell you how many moles of that compound you have. Push one of the buttons, and the whole process is reversed. Input the moles and see how many grams you have.

This amazing and comprehensive tool has the ability to find the molecular weight of any molecule. Even better, I will be continually updating this app with more and more features. And it's free, so why not...
