Answer : The mass of oxygen needed are 470.592 grams.
Solution : Given,
Mass of = 200.0 g
Molar mass of = 17 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of
The balanced chemical reaction is,
From the reaction, we conclude that
As, 4 mole of react with 5 mole of
So, 11.765 moles of react with moles of
Now we have to calculate the mass of
Therefore, the mass of oxygen needed are 470.592 grams.
