Answer : The volume of gas at STP produced are 45.0 L
Explanation :
First we have to calculate the moles of ammonium perchlorate.
Molar mass of = 117 g/mole
Now we have to calculate the moles of gas produced during the reaction.
The balanced chemical reaction is,
From the reaction we conclude that,
As, 3 moles of produces 3 moles of NO gas
So, 2.01 moles of produces 2.01 moles of NO gas
Now we have to calculate the volume of gas at STP.
At STP, 1 mole of substance occupy 22.4 L volume of gas.
As, 1 mole of NO gas occupy 22.4 L volume of gas.
So, 2.01 mole of NO gas occupy 2.01 × 22.4 L = 45.0 L volume of gas.
Therefore, the volume of gas at STP produced are 45.0 L
