Answer : The mass of required is 18.238 grams.
Explanation : Given,
Mass of = 83.10 g
Molar mass of = 146 g/mole
Molar mass of = 256.52 g/mole
The balanced chemical reaction is,
First we have to determine the moles of .
Now we have to determine the moles of .
From the balanced chemical reaction we conclude that,
As, 8 moles of produced from 1 mole of
So, 0.569 moles of produced from
mole of
Now we have to determine the mass of .
Therefore, the mass of required is 18.238 grams.
