Question

if a balloon filled with helium weighs 21.6 kg, knowing that helium's density is 0.18 kg/m3 then what is its volume?

Answer 1

Answer:

120 m³

Explanation:

Density is defined as the mass per unit volume. It is an intensive property,

in  mathematically defined as mass divided by volume:

Density = mass /Volume

Volume = Mass / Density

Volume = 21.6 kg / 0.18 kg/m³

              = 120 m³
