Clouds can weigh thousands of pounds due to their liquid water content. often this content is measured in grams per cubic meter (g/m3). assume that a cumulus cloud occupies a volume of one cubic kilometer, and its liquid water content is 0.2 g/m3. (a) what is the volume of this cloud in cubic miles? (b) how much does the water in the cloud weigh in pounds?
