SUMMARY
The maximum payload a helium balloon can lift at 0 degrees Celsius, when filled with 400m³ of helium, is 444 kg. This calculation is based on the buoyant force, which is determined by the volume of the balloon and the density difference between air and helium. The density of air at 0˚C is 1.29 kg/m³, while helium has a density of 0.18 kg/m³, resulting in a buoyant force that allows for this payload. If the balloon were filled with hydrogen, which has a density nearly half that of helium, it could lift a payload of 480 kg.
