But because there could be, like, 10 molecules with the exact same mass, we don't know exactly what they are, and if you want to clearly identify all of them, you have to do more experiments, which could take decades and billions of dollars.
No kako bi moglo biti, recimo, 10 molekula s istom masom, ne znamo točno koje su, pa ako ih želite sve jasno identificirati, treba raditi još eksperimenata, što bi moglo trajati desetljećima i stajati milijarde dolara.
