<u>Answer:</u> The mass of produced is 889.38 g
<u>Explanation:</u>
We are given:
Moles of Al = 8 mol
Moles of = 10 mol
For the given chemical reaction:
By stoichiometry of the reaction:
If 3 moles of chlorine gas reacts with 2 moles of Al
So, 10 moles of chlorine gas will react with = of Al
As the given amount of Al is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Thus, chlorine gas is considered a limiting reagent because it limits the formation of the product.
By the stoichiometry of the reaction:
If 3 moles of produces 2 mole of
So, 10 moles of will produce =
of
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
We know, molar mass of = 133.34 g/mol
Putting values in above equation, we get:
Hence, the mass of produced is 889.38 g
