question

A pioneer aeronaut is planning the design of a hot-air balloon. What volume of air at 100°C should be used if the balloon is to have a gross lifting power of 200 kg (defined as the mass of displaced air minus the mass of hot air)? The ambient temperature and pressure are 25°C and 1atm, and the average molecular weight of air is 29 g/mole, whereas that of the hot air is 32 g/mol (due to the presence of some CO_2).
