Calculate the number of structural particles in 44.8 liters of oxygen.

V (O2) = 44.8 liters.
Let us determine the number of structural oxygen particles. We write down the solution.
We use the following formula.
N = n * Na.
Where N is the number of molecules.
n is the amount of substance.
Na – Avogardo’s number, equal to 6.02 * 10’23.
We find the amount of substance.
n = V / Vm = 44.8: 22.4 = 2 mol.
N = 2 * 6.02 * 10’23 = 12.04 * 10’23 molecules.
Next, let’s determine the number of atoms. Since there are 2 oxygen atoms, we multiply by 2.
N = 2 * 12.04 * 10’23 = 24.08 * 10’23.
Answer: N = 12.04 * 10’23 molecules; N = 24.08 * 10’23 atoms.
