8. Balloons are still used to deploy sensors that monitor meteorological phenomena and the chemistry of the atmosphere. It is possible to investigate some of the technicalities of ballooning by using the perfect gas law. Suppose your balloon has a radius of 3.0 m and that it is spherical. i) What amount of H₂ (in moles) is needed to inflate the balloon to 1.0 atm in an ambient temperature of 25°C at sea level? ii) What mass can the balloon lift (the payload) at sea level, where the mass density of air is 1.22 kg/m³

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
