Answer:
1.38 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2.2 atm, V1 = 2.5L ,
P2 = ? , V2 = 4L
2.2 Ă— 2.5 Â = P2 Ă— 4
Divide both sides by 4
P2 = 5.5 Ă· 4
P2 = 1.38 atm
