The Party Guy, Mr. Balloon, is making animal figures out of long thin balloons that he twists into different shapes. Assume that the balloons are of uniform thickness, and that twisting them has a negligible effect on the volume of gas inside them. Therefore, the length of a balloon is proportional to its volume.Mr. Balloon makes a doggie balloon out of a 2.0 meter balloon, and a butterfly out of a 1.5 meter balloon. The butterfly contains 3.5 moles of gas. How many moles are in the doggie balloon?
