A consumer upset with the latest trend of postal rate increases has decided to try to send letters by balloon even though they may not reach their intended destinations. A 66400 cm³ gas-filled balloon will provide enough lift for a 46.8 g package to be accelerated upward at a rate of 3.40 m/s?. For these circumstances, calculate the density of the gas the consumer fills the balloon with. The acceleration due to gravity is g = 9.81 m/s² and the density of air is Pair = 1.16 kg/m³. Neglect the mass of the balloon material and the volume of the package. kg/m³
