Molecules

Molecules are the building blocks of matter. From the air we breathe to the ground beneath our feet to the processes of life, everything depends on the underlying chemical species. Wolfram|Alpha has information such as chemical structure, molecular formula, molar mass and much more for a vast array of different chemical compounds.
