The table below is calculated from the molecular formula CNa2O3. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the metallic element Na. The material behaves as an inorganic salt: it is non-volatile, generally water-soluble, and leaves an inorganic residue on ignition.
At 105.99 g/mol the molar mass is in the small-molecule range, where volatility and dust generation are the practical handling concerns.
