Question

If air has a density of 1.225 kg/m3, what is the mass of the air in a hot air balloon that has a volume of 2,800

m3?

Answer 1

The answer is 3430 kg

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 2800 m³

density = 1.225 kg/m³

We have

mass = 2800 × 1.225

We have the final answer as

3430 kg
