A spherical balloon is made from a material whose mass is 3.40 kg. The thickness of the material is negligible compared to the 1.40 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 280 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.
