If an average cloud has a density of 0.5 g/m3 and has a volume of 1,000,000,000 m3, what is the weight of an average cloud

If you have (1 x 10⁹) cubic meters of volume, and 1/2 gram of mass

in each cubic meter, then you have

(1/2 x 10⁹) grams = (5 x 10⁸) grams = (5 x 10⁵) kilograms of mass.

On Earth, that mass weighs 4,900,000 newtons.

(about 1,102,300 pounds)

(about 551 tons)
