Za izračun števila gramov kalijevega karbonata potrebujemo uporabiti formulo: masa = molarna koncentracija (M) × volumen (L) × molarna masa (g/mol). Molarna masa \( \mathrm{K}_{2} \mathrm{CO}_{3} \) je približno 138,21 g/mol. Tako v našem primeru: \( masa = 0,750 \mathrm{~mol/L} \times 2,50 \mathrm{~L} \times 138,21 \mathrm{~g/mol} \) = 260,15 g. Torej, potrebujete približno 260,15 gramov \( \mathrm{K}_{2} \mathrm{CO}_{3} \). Kako zabavno je delati preproste kemijske izračune! Vsakič, ko pripravljate raztopine, ste kot kemični kuhar, ki spreminja elemente in ustvarja nekaj novega. Uživajte v tej kemijski avanturi!
