Structure to properties

A SMILES to its formula, molar mass, exact mass, and isotope pattern. Invalid valence is flagged, never guessed.

SMILES → formula → mass
Deterministic transcription, no external lookup. An impossible structure returns an error, not a number.

Molarity, mass and volume conversion
Convert between molarity, mass, volume, and moles for a reagent, in any direction.
Molar mass, grams and moles
Type an element or formula (Sb, NaCl, C6H12O6) and convert grams to moles. Molar mass is computed from cited atomic weights.
