What is the volume of a balloon filled with hydrogen if the mass of the gas is 2.7 kg?


m = 2.7 kilograms is the mass of hydrogen in the balloon;

ro = 0.09 kilogram / cubic meter is the density of hydrogen.

It is required to determine V (cubic meter) – the volume of the balloon.

To determine the volume of a balloon, you need to use the following formula:

m = ro * V, hence:

V = m / ro = 2.7 / 0.09 = 30 cubic meters.

Answer: the volume of the balloon is 30 cubic meters.
