A gas sample of #Xe# occupies 10-liter balloon at 27°C under a pressure of 1.2 atm. Approximately what volume would the gas occupy at 350 K at 2 atm of pressure?
The gas would occupy approximately 7 L.
This is an example of a Combined Gas Laws problem.
#color(blue)(|bar(ul((P_1V_1)/T_1 = (P_2V_2)/T_2|)#
We can rearrange this formula to get
#V_2 = V_1 × P_1/P_2 × T_2/T_1#
Your data are:
The volume is approximately 7 L.
