A spherical balloon is made from a material whose mass is 3.03 kg . The thickness of the material is negligible compared to the 1.67-m
radius of the balloon. The balloon is filled with helium ( He ) at a temperature of 275 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^(3). Find the absolute pressure of the helium gas.
