Passage - I : Helium is stored in cylinders, each cylinder having a volume 1.5 m^(3) at a gauge pressure 1.5 xx 10^(6) N//m^(2). A balloon is filled with Helium at atmospheric pressure to a volume 600 m^3, using the gas stored in the cylinders. Temperature of Helium inside the balloon and that of the surrounding air are both 27°C. Given that density of air at 27°C and at atmospheric pressure is 1.2 "kg"//m^(3) and atmospheric pressure is 10^(5) N//m^(2), answer the following questions. [use mass of Helium as 4 g/mol, R=8.3 J/(mol-K) and g=10 m//s^(2) ] Number of cylinders required to fill the balloon are
