what the numbers on a vial label mean

UnitConfusionAnalystCommunity Seed

the label says a mass, which i now understand is the total amount of powder in there, not a concentration. concentration only exists once you add liquid.

is that right? because it took me embarrassingly long to work out and i suspect im not the only one

    That's exactly right and it's the most common misreading. The vial states total mass. Concentration is something you create when you reconstitute.

    Good, at least I'm not misunderstanding it any more.
