The balloon contains 0.30 {\rm mol} of helium starts at a pressure of 115 {\rm kPa} and rises to an altitude where the pressure is 55.0 {\rm kPa}, maintaining a constant 300 {\rm K} temperature.

(A)By what factor does its volume increase?

(B)How much work does the gas in the balloon do?

find the moles of helium from

PV=nRT

Now,knowing the moles, find the volume at the altitude. PV=nRT, solving for volume
