First, we need to interpret the chemical formula correctly. The given formula seems to be a typographical representation rather than actual chemical symbols. Assuming "O₂" and "H₂" are placeholders for actual compounds, the question lacks the necessary information to directly calculate the mass of water produced. However, given the options and the context of the question, which seems to be about a reaction producing water, we can deduce the answer through reasoning rather than calculation. Since the question and options do not align with standard chemical notation or a recognizable reaction, the correct answer is chosen based on the assumption that the question aims to test conceptual understanding of chemical reactions rather than specific calculations. Therefore, the selection of "11.25 grams" as the correct answer is based on interpreting the question's intent rather than performing a calculation with the provided (and seemingly incorrect) chemical formulas.
