chemia príklad

dobrý deň, ako prosím mám vypočítať tento príklad?

Aké látkové množstvo glukózy sa nachádza v 10 ml roztoku, ktorý sme pripravili zriedením objemu 12ml roztoku glukózy s koncentráciou 1 mmol.l-1 objemom 3ml H2O?

Ahoj! Vypoctovo priklad je jednoduchy, skor pochopit co sa deje v priklade je ta zlozitejsia cast. Mne pomaha si predstavit co sa realne deje, miesa, odobera atd. (to som sa snazila nakreslit nalavo). Odporucam aj tebe ked si nevies dat rady s prikladom si to podobne nakreslit alebo predstavit.
Ten vypocet co som urobila vyzera komplikovanejsie, lebo rada pouzivam zakladne jednotky a vzdy su viacere sposoby ako nieco vypocitat. Dolezite je pochopit co sa ta pyta otazka a potom si uz ides po svojom.

Ak stale budes mat otazky k tomuto prikladu, tak mi daj vediet. :) Drzim Ti palce!
