These tasks: V (volume of the considered vessel) = 8 l (8 * 10 ^ -3 m3); N (number of gas molecules in a vessel) = 2.4 * 10 ^ 24 molecules.
The concentration of molecules can be calculated using the formula: n = N / V.
Let’s make a calculation: n = 2.4 * 10 ^ 24 / (8 * 10 ^ -3) = 3 * 10 ^ 26 m-3.
Answer: In the vessel under consideration, the concentration of gas molecules is 3 * 10 ^ 26 m-3.
