He got 94%. The professor wrote: “Veliki napredak!”

Luka was a good chemistry student—until the chapter on stoichiometry hit. Balancing equations came naturally, but the moment his professor introduced mol , maseni udio , titracija , and iskorištenje reakcije , his grades plummeted.

Luka’s jaw dropped. It wasn’t magic—it was .

One evening, while searching online for “rješenja zadataka stehiometrija” , he stumbled upon a PDF: . He hesitated. “Using solved problems feels like cheating,” he thought. But he downloaded it anyway.

After failing the first stoichiometry quiz, Luka felt defeated. Every problem in the workbook seemed to twist the same formula into a puzzle with missing pieces.

He picked a problem he had failed before: “Izračunaj masu vode koja nastaje izgaranjem 10 g metana.”

From that day on, Luka didn’t just survive stoichiometry—he started helping classmates who were where he used to be. And he always told them: “Nabavi Sikiricu – ali nemoj samo prepisivati. Prati put. Moli su ključ.” The Sikirica – Stehiometrija: Rješenja zadataka PDF is a powerful tool—not because it gives answers, but because it teaches how to think through stoichiometry problems. Use it as a guide, not a crutch, and you’ll turn confusion into confidence.

Then: 1 mol CH₄ → 2 mol H₂O Molar mass CH₄ = 16 g/mol → 10 g = 0.625 mol 0.625 mol CH₄ → 1.25 mol H₂O → 1.25 × 18 = 22.5 g H₂O.
