Calculate the lift of a 15 m3 balloon filled with hydrogen.

Initial data: V (volume of the considered sphere) = 15m3; the weight of the ball shell is not included.
Reference data: ρ1 (air density, 20 ºС) = 1.204 kg / m3; ρ2 (hydrogen density) = 0.0898 kg / m3; g (acceleration due to gravity) = 9.81 m / s2.
The lifting force of the ball can be calculated by the formula: Fa = (ρ1 – ρ2) * g * V.
Let’s make a calculation: Fa = (1.204 – 0.0898) * 9.81 * 15m3 = 177155.387Н
