Aweather balloon holds 2,000 cubic meters of helium. the density of helium is 0.1765 kilograms per cubic meter. how many kilograms of helium does the balloon contain?

A balloon contains 353 kg Helium.

Step-by-step explanation:

A weather balloon holds 2000 cubic meters of helium.

Density of Helium = 0.1765 kilograms per cubic meter.

Then we have to calculate the weight of helium in the balloon.

Since

Now we put the values in the formula to get the mass of Helium.

Mass = 2000×0.1765 = 353 Kg.

Therefore 353 Kilograms of Helium is contained in a balloon.
