2. A spherical balloon is made from a material whose mass is 2.90 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 300 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m and the molar mass of helium is 4.0026x10-3 kg/mol. Find the absolute pressure of the helium gas. Pa
