Step-by-Step Solution
Balance the chemical equation: 2H₂ + O₂ → 2H₂O
Convert given quantity to moles: 25.0 g H₂O × (1 mol/18.02 g) = 1.39 mol H₂O
Use mole ratios from balanced equation: 1.39 mol H₂O × (2 mol H₂/2 mol H₂O) = 1.39 mol H₂
Convert moles to desired units: 1.39 mol H₂ × (2.02 g/mol) = 2.81 g H₂

Example: Mole to Gram Conversion
Convert 2.5 moles of NaCl to grams:
Find molar mass of NaCl: Na (22.99 g/mol) + Cl (35.45 g/mol) = 58.44 g/mol
Multiply moles by molar mass: 2.5 mol × 58.44 g/mol = 146.1 g
Final answer: 2.5 moles NaCl = 146.1 grams NaCl
