Aspherical balloon is made from a material whose mass is 3.30 kg. the thickness of the material is negligible compared to the 1.25 m radius of the balloon. the balloon is filled with helium (he) at a temperature of 345 k and just floats in air, neither rising nor falling. the density of the surrounding air is 1.19 kg/m³ and the molar mass of helium is 4.0026×10-3 kg/mol. find the absolute pressure of the helium gas.
