A high-altitude balloon contains 97.5 L of helium gas at 95.8 kPa. What is the volume when the balloon rises to an altitude where the pressure is only 21.5 kPa? (Assume that the temperature remains constant.)

P*V = constant at constant T.

It's somebody's Law. Boyle's?

P1*V1 = P2*V2

You aleady know P1, P2 and V1.

Solve for V2.
