the vessel is filled with a mixture of gases containing 21 g of nitrogen and 176 g of oxygen at a known concentration of the mixture equal to 3*10^20 cm^-3.

To solve the problem, it is necessary to determine the volume of the vessel and the density of the mixture.

Let's use Dalton's law, according to which the total pressure of a mixture of gases is equal to the sum of the pressures of each gas in the mixture at the same temperature and volume.

It is known that the total mass of gases in the vessel is 21 g + 176 g = 197 g. In this case, the mass fraction of nitrogen in the mixture is:

21 g / 197 g = 0.1066

And the mass fraction of oxygen:

176 g / 197 g = 0.8934

Thus, we can determine the molar mass of a mixture of gases:

M = 0.1066 * M(N2) + 0.8934 * M(O2) ≈ 32 g/mol

where M(N2) is the molar mass of nitrogen, M(O2) is the molar mass of oxygen.

The concentration of the gas mixture is also known:

n/V = 3*10^20 cm^-3

where n is the number of moles of gases, V is the volume of the vessel.

Thus, the volume of the vessel can be determined:

V = n / (3*10^20 cm^-3)

n = m/M = 197 g / 32 g/mol ≈ 6.156 mol

V = 6.156 mol / (3*10^20 cm^-3) ≈ 2.05 * 10^-2 m^3

Finally, we can determine the density of the gas mixture:

ρ = m/V = 197 g / (2.05 * 10^-2 m^3) ≈ 9.61 kg/m^3

Thus, the volume of the vessel is approximately 2.05 * 10^-2 m^3, and the density of the gas mixture is approximately 9.61 kg/m^3.
