Passage-I : A cubical box of side 1 m contains helium gas (atomic weight 4) at a pressure of 100 N//m^2. During an observation time of 1 s, an atom travelling with the root mean square speed parallel to one of its edges of the cube, was found to make 500 collisions with a particular wall, without any collision with other atoms. Taking R = ( 25//3) J//mol-K and k= 1.38 xx 10^(-23) J//K. What is the total mass of helium gas in the box
