T = constant
initial volume (V1) = 67 L
initial pressure(P1) = 1.04 atm
final pressure(P2) = 0.047 atm
final volume (V2) = ?
P1V1 = P2V2
(67*1.04) = 0.047*V2
V2 = 1482.55 L

answer question clear and complete 3) A weather balloon contains 12.0 mº of hydrogen gas when the balloon is released from a location at which the temperature is 22.0°C and the ambient air pressure is 101 kPa. The balloon rises to a higher altitude where the temperature is -30.0°C and the ambient air pressure is 20.0 kPa. If the balloon is free to expand so that the pressure of the gas inside is equal to the ambient pressure outside, what...
