Final answer:
To calculate the mole ratio of H₂O to KAl(SO₄)₂, the number of water molecules in the hydrate must be known. For a common hydrate, KAl(SO₄)₂ · 12H₂O, the mole ratio is 12:1, but since this ratio is not among the provided options, we cannot confirm the correct answer without further details.
Step-by-step explanation:
Steps to Determine the Mole Ratio of H₂O to KAl(SO₄)₂
First, we need to identify the formula for hydrated potassium aluminum sulfate, which typically has water molecules associated with it. The formula is often written as KAl(SO₄)₂ · xH₂O, where 'x' represents the number of water molecules. For this question, it's essential to know the value of 'x' to find the correct mole ratio. Without this information, we cannot provide an accurate answer. However, one of the common hydrates is KAl(SO₄)₂ · 12H₂O. Assuming we are dealing with this hydrate, we could draw a conclusion.
Mole Ratio Calculation (Assuming 12 Molecules of H₂O)
The mole ratio of H₂O to anhydrous KAl(SO₄)₂ in the hydrate KAl(SO₄)₂ · 12H₂O is 12:1. Therefore, for every mole of KAl(SO₄)₂, there are 12 moles of H₂O.
If the question refers to the specific hydrate KAl(SO₄)₂ · 12H₂O, the answer would be that the mole ratio is not 1:1 (A), 1:2 (B), nor 2:1 (C), and thus none of the provided options are correct. We would need more information to provide a precise answer.
