1 mole of any gas under STP has volume 22.4 L,
we have 2 mole of gas, so volume of container should be 2*22.4 L= 44.8 L

Fission and fusion Releases the most energy
Given :
Volume of stock solution, .
Volume of diluted solution, .
Molarity of diluted solution, .
To Find :
The concentration of the stock solution.
Solution :
We know, dilution factor is given by :
....1)
and ....2)
Putting volume in above equation, we get :
D.F = 400/20
D.F = 20
Putting value of D.F in equation 2) we get :
The concentration of stock solution is nearest to 30 M.
Therefore, the correct option is 1) 30 M.
