Mathematical Formula & Logic
Step-by-Step Worked Calculation
Scenario: Oxygen Release from Water Electrolysis
Find mass of Oxygen (O2) produced from 36 grams of Water (H2O) under 2 H2O -> 2 H2 + O2.
Step 1: Balance equation coefficients: 2 moles of H2O yield 1 mole of O2 (ratio = 1/2).
Step 2: Convert H2O mass to moles: 36 g / 18.015 g/mol = 2.0 moles.
Step 3: Multiply by mole ratio to find O2 moles: 2.0 moles * (1 / 2) = 1.0 mole of O2.
Step 4: Convert O2 moles to mass: 1.0 mole * 31.998 g/mol = 32.0 grams of Oxygen.
