The average density of the balloon having a volume of 5.0 m³ is 0.4 kg/m³
The mass of the balloon with the enclosed gas = 2.0 kg
The volume of the balloon = 5 m³
The density of the air = 1.3 kg/m³
The density of the balloon can be found using the formula
ρ = m/v
where ρ is the density of the balloon
m is the mass of the balloon
v is the volume of the balloon
Let us substitute the known values in the above formula, we get
ρ = 2 / 5
= 0.4
Thus, the density of the balloon is 0.4 kg/m³
