Hello!</h2>
The answer is: The new pressure is 1.67 atm.
<h2>
Why?</h2>
From the statement, we know that the temperature remains constant and the gas volume is changing, meaning that the new pressure will be different than the first pressure.
Since the temperature remains constant, we can calculate the new pressure using the Boyle's Law.
The Boyle's Law states that:

Where,
P is the pressure of the gas.
V is the volume of the gas.
Then, the given information is:

Remember, 1 L is equal to 1000 mL.
So,

So, calculating the new volume, we have:

Hence, the new pressure is 1.67 atm.
Have a nice day!
Answer:
I. The balloon has a volume of 22.4L
III. The balloon contains 6.022x10^23 molecules.
Explanation:
At stp, it has been proven that 1mole of a gas occupy 22.4L.
Therefore, option (i) is correct.
The molar mass N2 = 14.01 x 2 = 28.02g/mol
Number of mole of N2 = 1 mole
Mass of N2 =..?
Mass = mole x molar Mass
Mass of N2 = 1 x 28.02 = 28.02g.
The mass content of the balloon is 28.02g, therefore, option (ii) is wrong.
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of N2 also contains 6.02x10^23 molecules
Therefore, option (iii) is correct.
The correct options to the question are:
Option i and option iii
