Answer:
The pressure in container A is higher than container B.
Explanation:
Applying ideal gas law PV=nRT, With the equation we can predict volume V is inverse to pressure P, that means if volume increase, pressure decrease.
The volume in container B is half A, that means respectively, pressure is the double.
check it with the equation:
n=1/18=0.05
R=62.36 L*Torr/K*mol
T=273+20=293 K
V=0.02 L
P=nRT/V =0.056*62.36*293/0.01=102.3 torr
I hope my answer helps you
