The figure shows two connected flasks. The volume of flask-1 is twice that of flask-2. The system is filled with an ideal gas at temperatures of \(100\) K and \(200\) K, respectively. If the mass of the gas in flask-1 is \(m,\) what is the mass of the gas in flask-2 when the system reaches equilibrium?

      
1. \(m\)         
2. \(m/2\)    
3. \(m/4\)    
4. \(m/8\)
