Find the volume that 18 * 10 ^ 23 molecules of sulfur dioxide SO2 have

N = 18 * 10’23 molecules.
Let’s determine the volume of sulfur dioxide. 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, constant equal to 6.02 * 10’23.
We express the amount of substance.
n = N / Na.
n = 18 * 10’23 / 6.02 * 10’23 = 2.99 mol.
We find the volume of sulfur dioxide.
n = V / Vm.
V = n * Vm.
V = 2.99 mol * 22.4 l / mol = 66.98 l.
Answer: the volume of sulfur dioxide is 66.98 liters; the amount of sulfur dioxide substance is 2.99 mol.
