Chapter 18, Problem 18.63(choose chapter or problem)
A balloon whose volume is is to be filled with hydrogen at atmospheric pressure (a) If the hydrogen is stored in cylinders with volumes of at a gauge pressure of how many cylinders are required? Assume that the temperature of the hydrogen remains constant. (b) What is the total weight (in addition to the weight of the gas) that can be supported by the balloon if the gas in the balloon and the surrounding air are both at The molar mass of hydrogen is The density of air at and atmospheric pressure is See Chapter 12 for a discussion of buoyancy. (c) What weight could be supported if the balloon were filled with helium (molar mass ) instead of hydrogen, again at
