A weather balloon has a volume of 770 L when filled with helium at 8 ∘C at a pressure of 400 torr . What is the final volume, in liters, of the balloon, where the pressure is 0.21 atm and the temperature is − 47 ∘C, when the amount of gas does not change? Express your answer to two significant figures and include the appropriate units.
