Question #99885

Uranus is much larger than Earth, with a surface area of 8.10 × 1015m2with an atmosphere of low-density gases: 82.5% H2, 15.2% He, and 2.30% CH4. The acceleration due to gravity is similar to that on Earth, 8.70 m/s2, yet the atmospheric pressure on Uranus is estimated to exceed 1.00 ×108Pa.
What is the mass of the atmosphere on Uranus? answer in kg

Expert’s answer

m•g = F = p•Sm = p•S/g = 108•8,1•1015/8,7 = 9,31 • 1022 kg
