A balloon contains 10 g of H₂ (2.01588 amu) gas. How many moles of argon gas (39.9480 amu) must be added so that the balloon will have exactly the same aero buoyancy (i.e., so that its weight will be equal to that of an equal volume of the surrounding air)?

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.
