1) Water vapor mixes with collected gas — collected gas is saturated with water vapor, so measured pressure must be corrected for vapor pressure.
2) Equal volumes have same particle count — Avogadro’s principle lets you relate gas volumes directly to mole ratios in reactions.
3) Incomplete reaction or side reactions — not all reactant converts to product (or side reactions consume some), so actual yield is below theoretical.
