Mass to formula calculator

If you have an accurate molecular mass, you might want to know what chemical formula would produce that mass. Guillaume Cottenceau in Henry Rzepa’s laboratory at Imperial College London wrote just such an application. Enter a precise molecular mass and it will work out chemical formula of the possible organic molecules that would have that mass.
