One mole of argon gas is confined to a 1.2-liter container at a pressure of 8 atm. The molar mass of argon is about 40 x10-³ kg/mol. The molar mass of He is about 4 x 10-³ kg/mol, 1 atm 1.013 x105 Pa and 1 L = 10-³m³, R =8.31 K/(kg K) 5 points (a) What is the rms speed of the argon atoms? (b) Compare your answer to the rms speed for helium atoms under the same conditions. Show your work and circle the choices below. 1. The rms speed of argon atoms is around half the rms speed of helium atoms. 2. The rms speed of argon atoms is around one third the rms speed of helium atoms. 3. The rms speed of argon atoms is equal to the rms speed of helium atoms.
