Answer 2

Calculation of Gas Pressure

To determine the pressure of the gas in the vessel, we can use the ideal gas law, which states that the pressure of a gas is directly proportional to its concentration, temperature, and the average square velocity of its molecules.

The formula for the ideal gas law is:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant - T is the temperature of the gas in Kelvin

In this case, we are given the average square velocity of the gas molecules (3.4 × 10^6 (m/s)^2), the concentration of the gas (6.2 × 10^24 m^-3), and the mass of one molecule (2.1 × 10^-25 kg).

To calculate the pressure, we need to convert the concentration to the number of moles using Avogadro's number (6.022 × 10^23 mol^-1). We can then rearrange the ideal gas law equation to solve for pressure:

P = (nRT) / V

Since we are not given the volume of the gas, we cannot calculate the pressure accurately without that information.
