SUMMARY
The discussion focuses on calculating the pressure of argon gas using its number density and root mean square (RMS) speed. The number density is given as 2.00 x 1025 atoms/m3, and the RMS speed is 455 m/s. The pressure can be calculated using the formula P = (1/3)(N/V)(m)(v2rms), where N is the number of particles, V is the volume, m is the mass of a single argon atom, and vrms is the RMS speed. To find the mass of argon, one must utilize Avogadro's law and the periodic table to determine the molar mass of argon.
