Ahelium-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 1.1kg/m^3 less than regular air, which means a cubic meter of helium can lift about 1.1kg. a blimp with a mass of 2.13 x 10^5kg can carry as much as 2 x 10^5m^3 of helium. if the average mass of a person with luggage is 10^2kg what is the number of passengers the blimp can carry
