Final answer:
To find the grams of Phosphoric Acid produced, convert the mass of K₃PO₄ to moles using its molar mass, and then use the stoichiometry of the balanced equation to find the moles and consequently the mass of H₃PO₄ produced. Without the molar masses or additional information, the exact mass cannot be calculated.
Step-by-step explanation:
To calculate the grams of Phosphoric Acid (H₃PO₄) produced in the reaction, we need to first write down the balanced chemical equation given: K₃PO₄ + 3HCl → 3KCl + H₃PO₄. The question doesn't specify the amount of HCl used or the amount of K₃PO₄ that reacted. However, let's assume the reaction goes to completion and uses 25g of K₃PO₄ (a usual assumption in stoichiometry problems if not otherwise specified), and stoichiometric amounts of HCl. To proceed, one would need to use the molar mass of K₃PO₄ to convert the given mass (25g) to moles. From the balanced equation, we can see that 1 mole of K₃PO₄ produces 1 mole of H₃PO₄. By finding the moles of K₃PO₄ used, we can directly find the moles of H₃PO₄ produced. Then, we multiply the moles of H₃PO₄ by its molar mass to get the mass in grams. Without the molar masses provided in the question, we cannot provide a quantitative answer. Please provide the molar masses or consult a periodic table to find them and complete the calculation.
