Answer : The grams of consumed is, 89.6 grams.
Solution : Given,
Mass of = 265 g
Molar mass of = 80 g/mole
Molar mass of = 28 g/mole
First we have to calculate the moles of .
The given balanced reaction is,
from the reaction, we conclude that
As, 1 mole of produces from 1 mole of
So, 3.2 moles of produces from 3.2 moles of
Now we have to calculate the mass of
Therefore, the grams of consumed is, 89.6 grams.
