Hello!
You need to calculate the volume of the container. To calculate the volume of this amount of N₂ gas we need to make the assumption that N₂ behaves like an ideal gas.
1 mole of an ideal gas under Standard Temperature and Pressure occupies 22,4 L so the calculations are as follows:
So, the volume of the container should be 1,028 L or more.
Have a nice day!

Explanation:
The intermediate energy level that the electron reached from the ground state is; n= 3.
<h3>What are energy levels in an atom?</h3>The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). Higher energy electrons have greater energy as you move out from the nucleus.
A region of space within an energy level known as an orbital is where an electron is most likely to be found.
The formula to get the higher level is Rydberg's formula;
1/λ = R(1/n₁² - 1/n₂²)
where;
R is rydberg constant = 1.097 × 10⁷ m⁻¹
We want to find the intermediate level where wavelength = 1281 nm = 1281 × 10⁻⁹ m
Thus;
n₂ = √(1/0.1112)
n₂ ≈ 3
