Question

Helium is a gas lighter than air that is used in balloons. The density of
helium is approximately 0.14 kilograms per cubic meter. You get 5 helium balloons for your 5th birthday, each with a volume of 14 cubic meters. How many kilograms of helium do the balloons contain, to the nearest hundredth?

Answer 1

Using proportions, given the density value, it is found that the ballons contain 9.8 kilograms of helium.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, we have that each ballon contain 0.14 kilograms per cubic meter.

You get 5 ballons, each with 14 cubic meters, hence the total volume is given by:

V = 5 x 14 = 70 m³.

Applying the density, we have that the total mass is given by:

M = 0.14 x 70 = 9.8 kilograms.
