To find the percent yield, first calculate the theoretical yield of phosphoric acid (H₃PO₄) using stoichiometry. The balanced equation is P₄O₁₀ + 6H₂O → 4H₃PO₄. Calculate moles of P₄O₁₀ and H₂O, find the limiting reactant, and use it to find the theoretical yield of H₃PO₄. Then, percent yield = (actual yield/theoretical yield) × 100%. The calculations show that the percent yield is 84.00%.
