DEMONSTRATION 2 — Formulation Scaling & Mass Balance AI-assisted educational sample; hypothetical data, no client or validated product claimed. For a proposed 100 kg blend: ingredient A 60%, B 25%, C 10%, D 5%. Total = 100%; quantities = 60, 25, 10 and 5 kg. For a 35 kg trial, multiply each fraction by 35: 21, 8.75, 3.50 and 1.75 kg; sum = 35 kg. If nonselective handling loss is assumed at 2%, packed output = 35 × 0.98 = 34.30 kg. At 0.5 kg per pack, that is 68 full packs plus 0.30 kg remainder. To target 100 kg packed, gross input = 100 / 0.98 = 102.0408 kg. Checks: distinguish percentage from mass, gross input from packed output, and theoretical yield from measured yield. Selective losses require component balances rather than proportional scaling. This is a calculation demonstration, not a finished recipe, safety assessment or shelf-life validation.
