A balloon contains 30.0 L of helium gas at 103 kPa. What is the volume of the helium when the balloon rises to an altitude where the pressure is only 25.0 kPa? Assume that the temperature remains constant

• Chem - ,

P1V1 = P2V2

• Chem - ,

P1V1=P2V2
P1=103kpa
V1=30.0L
P2=25.0kpa
V2=?
(103kpa)(30.0l)=(25.0kpa)(v2)
v2 = 124l
