I don’t know what you mean by “total amount” because ppm is a concentration
The spray is clearly delivering a set amount, but describing it in ppm. Since the volume and density of air inside then nose isn’t changing, you can treat the change as a count rather than concentration.
that tweet’s interpretation agrees with mine.
My understanding of the tweet’s model is that [actual released amount] * [8 hours] = 0.11ppm, so [released amount] = 0.11/8.
I still don’t understand your number. Could you expand the equation behind “If NO is produced and reacts immediately, say in 20 seconds, this means the concentration achieved is 19.8 ppm”?
