Question

You have four fixed-volume containers at STP. Container A has 0.5 mol of gas in 11.2 L. Container B has 2 mol of gas in 22.4 L. Container C has 1 mol of gas in 22.4 L. Container D has 2 mol of gas in 11.2 L. Which of the four containers have equal pressures?
A and C

A and B

B and C

C and D

Answer 1

Container A has 0.5 mol of gas in 11.2 L.
P = nRT/V = 0.5(0.08206)(273.15) / 11.2 = 1 atm

Container B has 2 mol of gas in 22.4 L.
P = nRT/V = 2(0.08206)(273.15) / 22.4 = 2 atm

Container C has 1 mol ofgas in 22.4 L. P = nRT/V = 1(0.08206)(273.15) / 22.4 =1 atm

Container D has 2 mol of gas in 11.2 L.
P = nRT/V = 2(0.08206)(273.15) / 11.2 = 4 atm

Therefore, the correct answer from the choices is the first option, container A and C has equal pressures.
