2. A hot air balloon has a volume of 3123 mº, and the temperature inside the balloon is 108.0 °C.
The pressure and outside temperature are 744 Torr and 20.0 °C, respectively. Assuming 28.9
g/mol, determine the amount of payload (kg) that could be lifted by this balloon if the mass of
the balloon is 144 kg. Hot air is the lifting medium in this case. A hot air balloon has a hole in
the bottom to heat the air. This means that both the pressure and the molar mass of air is the
same both inside and outside the balloon.
