Answer:

Given your reaction conditions, your volume of gas is in a piston. The gas should expand to a #~=8*L# volume.

Explanation:

I think you have asked this question before; it is still suspect because we must assume that the gas is enclosed in a container whose volume can change, i.e. a piston.

Charles' Law states that #"Volume "prop" Temperature"#, i.e. #VpropT#, or #V=kT#.

Solving for #k#, #V_1/T_1=V_2/T_2#, and here we must use #" Absolute Temperature"# #=# #""^@C + 273.15*K#.

#V_2=(V_1T_2)/T_1# #=# #(5.00*Lxx373.15*K)/(223.15*K)# #=# #??L#
