C'est très problèmatique les erreurs d'arrondi !

Everything is outdated. EVERYTHING.

Molecule.from_string("OH2CMgUut") throws KeyError: 'C'.

Molecule.calculate_oxidation() is missing the element C in the returned dictionary.

As seen in the image below, the molar mass of molecule used for mass <-> mole conversion did update from H2 to HCl.

Make our website great again!
More precisely: better CSS and better JS (probably react or angular).

Good luck to us.

The number of structural isomers of alkanes are only accurate up to 6:

• Heptane is said to have 7 structural isomers, while according to wikipedia

Heptane has nine isomers

• Octane is said to have 11 isomers, while

Octane has 18 structural isomers

The synthesis equation of acetylsalicylic acid (aka aspirin, C9H8O4) through by reacting salicylic acid (C7H6O3) with ethanoic anhydride (C4H6O3) should be perfectly valid; yet CHEMaths clearly thinks it consists of 2 separate reactions.

Mass input is processed as mole input.
