Answer : The theoretical yield of ammonia produced are, 242.76 g
Solution : Given,
Mass of hydrogen gas = 100 g
Mass of nitrogen gas = 200 g
Molar mass of
= 2 g/mole
Molar mass of
= 28 g/mole
First we have to calculate the moles of
and
.
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 3 moles of
react with 1 mole of
So, 50 moles of
react with
moles of
That means, in the given balanced reaction,
is a limiting reagent because it limits the formation of products and
is an excess reagent.
Hence, the
is the limiting reagent.
Now we have to calculate the moles of
.
As, 1 mole of
react with 2 moles of
So, 7.14 moles of
react with
moles of
Now we have to calculate the mass of
.
Therefore, the theoretical yield of ammonia produced are, 242.76 g
