Determine what volume 2.4 * 10 ^ 24 fluorine molecules occupy under normal conditions.

It is necessary to determine what volume, under normal conditions, is occupied by N = 2.4 * 10 ^ 24 fluorine molecules. To solve this problem, it is necessary to calculate the number n moles of gas, in a given number of molecules N. For this, the total number of molecules, we divide by Avogadro’s number NA = 6 * 10 ^ 23.

n = N: NA = 2.4 * 10 ^ 24: 6 * 10 ^ 23 = 40 mol.

It is known from the course of chemistry that 1 mol of gas under normal conditions takes a volume of V = 22.4 liters. This means the required volume v is equal to.

v = n * V = 40 mol * 22.4 l = 896 l.
