| It is necessary to determine the number of atoms contained in 1 liter of nitrogen.

We know the following formula

n = N / Na = V / Vm

Where N is the number of atoms,

Na is Avogardo’s constant number, three equal to 6.02 × 10 ^ 23.

V is the volume of gas,

V m is the molar volume, which has a constant value of 22.4 g / mol.

We express from this formula N and get the following:

N = Na × V / Vm

We substitute and get the following solution:

N = 6.02 × 10 ^ 23 × 1 / 22.4 = 0.27 × 10 ^ 23 = 2.7 × 10 ^ 22.

Answer: the number of atoms in 1 liter of nitrogen is 2.7 × 10 ^ 22.
