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.
Luka’s jaw dropped. It wasn’t magic—it was .
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.
That night, he didn’t just copy answers. He noticed the structure: each solution showed a logical flow—from reaction equation to mole ratio, from given data to unknown variable. Step-by-step. Clean. Logical.
