Answer:
The buoyancy force still just depends on the density of the air and the volume of the object. So, why does a helium balloon float? The only thing special about a helium gas is that it has a significantly lower density than air (with a density of 0.179 kg/m3 for helium and 1.2 kg/m3 for air)
