Calling a scrappy scan, of unknown provenance, added to the back of a scanned paper, a "supporting results annex" is stretching academic terminology a little too far.
MagnegasTM was ordinary producer gas (a carbon monoxide & hydrogen mix), albeit made in an odd way. There is no g/mol figure for the MagneHTM samples that were analysed for gas content, in the actual paper.
Note that carbon monoxide has a molar mass of 28.010 g/mol.
