<u>Answer:</u> The mass of aluminium chloride produced is 12.17 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
- <u>For aluminium oxide:</u>
Given mass of aluminium oxide = 10.0 g
Molar mass of aluminium oxide = 102 g/mol
Putting values in equation 1, we get:
Given mass of HCl = 10 g
Molar mass of HCl = 36.5 g/mol
Putting values in equation 1, we get:
The given chemical equation follows:
By Stoichiometry of the reaction:
6 moles of HCl reacts with 1 mole of aluminium oxide
So, 0.274 moles of HCl will react with = of aluminium oxide
As, given amount of aluminium oxide is more than the required amount. So, it is considered as an excess reagent.
Thus, HCl is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
6 moles of HCl produces 2 moles of aluminium chloride
So, 0.274 moles of HCl will produce = of aluminium chloride
Now, calculating the mass of aluminium chloride from equation 1, we get:
Molar mass of aluminium chloride = 133.34 g/mol
Moles of aluminium chloride = 0.0913 moles
Putting values in equation 1, we get:
Hence, the mass of aluminium chloride produced is 12.17 grams
