A spherical helium balloon 11 m in diameter is at ambient temperature and pressure, 15 degrees Celsius and 100 kPa. How much helium does it contain? It can list a total mass of balanced atmospheric air. How much mass of the balloon fabric & cage can then be lifted?
Here is my work but I'm unsure if it's correct. If someone could let me know I would really appreciate it. I also don't know how to answer the second part of the problem at all. Thanks in advance!
r = 5.5 m
T = 15°C = 288.15 K
P = 100 kPa = 100 kN/m
R = .287 kN m/kg K
m = PV/RT = 842.69 kg Helium
