<u>Answer:</u> The mass of produced is 45.22 g
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.
Excess reagent is defined as the reagent which is left behind after the completion of the reaction.
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
- <u>For </u>
<u>:</u>
Given mass of = 62.0 g
Molar mass of = 124 g/mol
Putting values in equation 1, we get:
- <u>For </u>
<u>:</u>
Given mass of = 4.00 g
Molar mass of = 2 g/mol
Putting values in equation 1, we get:
The chemical equation follows:
By stoichiometry of the reaction:
If 6 moles of hydrogen gas reacts with 1 mole of
So, 2 moles of hydrogen gas will react with = of
As the given amount of is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Thus, hydrogen gas is considered a limiting reagent because it limits the formation of the product.
By the stoichiometry of the reaction:
If 6 moles of produces 4 mole of
So, 2 moles of will produce =
of
We know, molar mass of = 34 g/mol
Putting values in equation 1, we get:
Hence, the mass of produced is 45.22 g
