A balloon filled with hydrogen has a mass of 450kg. How much weight can it lift if its volume is 1600m3?

It follows from the condition that the volume of air displaced by a balloon with hydrogen inside occupies 1600 m3.

From the tables we find the mass of 1 m3 of air = 1.29 kg.

Next, we find the mass of air displaced by the balloon:

1600 * 1.29 kg = 2064 kg.

To balance the position of the ball, ballast must be suspended from it. Determine the amount of ballast:

2064 kg – 450 kg = 1614 kg.

This will be the mass that the balloon can lift.

Answer: 1614 kg.
