Parts per million or similar means something. But also only if you add by weight, by volume, by mole, or by equivalent. But that is not what you said.
“parts per gram” mean NOTHING.
Alternatively. % means something, but again, only if you say my weight, or volume, or mole, or equivalent. Which I said BY WEIGHT right up in the beginning.
What I said is scientifically meaningful. You, trying to act like you knew more than me, spit out a meaningless description of a measurement and said, “that’s how it’s measured.” Did you make a mistake? If so, own it.
And to be clearer, a “part per gram” is not a “mg per gram” or a “mole per gram” or a “milliequivalent per gram” - all of which would actually have clear scientific meaning. But none of the above is what you said. You said “parts per gram” and “that’s how it’s measured.”
Sorry. That’s just wrong.
I actually did make one math mistake which no one has pointed out so far. Not sure if anyone caught it. Did you?
