At an altitude for which ambient pressure is #0.700*atm#, and a temperature of #270.15*K#, a balloon contains #3.00*mol# of gas... What is the volume of the balloon....?

Answer:

There is no question here, but your neighbour, the balloonist, has filled a balloon with approx. #100*L# volume.

Explanation:

Of course, he may have heated the contents of the balloon somehow, but we must assume #T=270*K#, so..........

#V=(nRT)/P=(3.00*molxx0.0821*(L*atm)/(K*mol)xx270.15*K)/(0.700*atm)#

#~=100*L.#

We have assumed the temperature, and know that the balloon expanded against a #0.700*atm# pressure. Because the balloon is apparently floating, what is the probable filling gas?
