Density of mixture = (mass of hydrogen + mass of helium)/volume of balloon
= [(density of hydrogen x volume of balloon ) +( density of helium x volume of balloon)]/(volume of balloon)
= destiny of hydrogen + density of helium
= 0.179 + 0.090
= 0.269 kg/m³

A large balloon of mass 226 kg is filled with helium gas until its volume is 325 m3. Assume the density of air is 1.20 kg/m3 and the density of helium is 0.179 kg/m3. (a) Calculate the buoyant force acting on the balloon. (b) Find the net force on the balloon and determine whether the balloon will rise or fall after it is released. (c) What maximum additional mass can the balloon support in equilibrium? (d) If you skip (c),...
