A helium-filled blimp stays aloft since helium is less dense than regular air, so helium will rise above regular
air. The density of helium is about 1.1 kg/m less than regular air, which means a cubic meter of helium
can lift about 1.1 kg. A blimp with a mass of 2.13 x 10 kg can carry as much as 2 x 10 m of helium.
If the average mass of a person with luggage is 10²kg, what is the number of passengers the blimp can
carry?
