Question:
How many moles of water vapour are evolved when 1 mole of hydrated aluminium chloride dimer (Al2Cl6.12H2O) is strongly heated?
Answer:
To determine the number of moles of water vapor evolved when 1 mole of hydrated aluminium chloride dimer (Al2Cl6.12H2O) is strongly heated, we need to understand the stoichiometry of the reaction.
The chemical formula of the hydrated aluminium chloride dimer suggests that there are 12 moles of water molecules (H2O) present for every 1 mole of Al2Cl6. Therefore, the reaction can be represented as:
Al2Cl6.12H2O(s) → Al2Cl6(s) + 12H2O(g)
This indicates that for every mole of Al2Cl6.12H2O, 12 moles of water vapor will be released.
Calculation:
Given: 1 mole of Al2Cl6.12H2O
Using the stoichiometry of the reaction, we can determine the number of moles of water vapor evolved by multiplying the mole ratio by the number of moles of Al2Cl6.12H2O.
Number of moles of water vapor = 12 moles of water vapor/mol of Al2Cl6.12H2O × 1 mol Al2Cl6.12H2O
Number of moles of water vapor = 12 moles
Therefore, when 1 mole of hydrated aluminium chloride dimer (Al2Cl6.12H2O) is strongly heated, 12 moles of water vapor are evolved.
Final Answer:
The correct answer is '12' moles of water vapor.

Final Answer:
The correct answer is '12' moles of water vapor.
