Answer : The mass of
required is, 61.82 grams.
Explanation :
First we have to calculate the moles of


Now we have to calculate the moles of
.
The balanced chemical equation is:

From the balanced reaction we conclude that
As, 1 mole of
react with 6 mole of

So, 0.322 moles of
react with
moles of

Now we have to calculate the mass of


Molar mass of
= 32 g/mole

Therefore, the mass of
required is, 61.82 grams.
