Do you really believe this engineer, who royally screwed up the mixing, using 40x the correct amount, would have coped with the molecular concentration calculations?
Having demonstrated themseIf to be utterly defeated by 100ppm, it is unreasonable to believe they'd have aced molecular concentrations, never mind finding it "far easier" as you claim.
As the manufacturer knows the density of their own product, and using as standard fuel density, Chu Chu's suggestion of the manufacturer specifying 1kg of product to 7,760kg of fuel is easily the best suggestion, as that is the very simplest calculation by a long way.
Inside every vexing problem is a very simple solution (ha!) struggling to be seen!
