Final answer:
Without a specific chemical reaction that shows ammonium chloride producing water, it is impossible to determine how many grams of water are produced from 76.4 grams of ammonium chloride since common reactions of NH4Cl do not produce H2O as a product.
Step-by-step explanation:
To determine the amount of water produced from 76.4 grams of ammonium chloride (NH4Cl), we would need the chemical equation that describes the reaction involving ammonium chloride and its products. However, in the normal decomposition of ammonium chloride, water is not a product. Ammonium chloride typically decomposes into ammonia (NH3) and hydrochloric acid (HCl), not water (H2O). Therefore, based on common reactions involving NH4Cl, one would not expect to produce water directly.
If there's a specific reaction where water is produced from NH4Cl, the balanced chemical equation would be paramount in solving this problem. One would have to use stoichiometry to convert the mass of NH4Cl to moles, and then use the mole ratio from the balanced equation to find the moles of H2O produced. The final step would be to convert the moles of water to grams using the molar mass of water (18.02 g/mol).
Without the specific reaction, it is impossible to provide an exact number of grams of water produced from 76.4 grams of ammonium chloride. A clear description of the full reaction is necessary to answer this question accurately.
