I realise that the characters think that aura is "life energy", but that is most likely just because they haven't made any real effort to study aura in any concrete way. Hell, they probably haven't even done as much as we have here. Like I said, the reason I believe the characters don't weigh more despite the amount of aura they should possess is because it isn't aura. Instead it is chemical energy which has yet to be synthesised into aura. The aura itself is an entirely different state of matter, not unlike plasma, but without its intense heat and light. Because plasma can hold different levels of energy however, this may explain why Gon for instance is able to hold up his fist despite the immense levels of aura being produced when charging his jajanken or Uvo with his Big Bang Impact. Rather than producing massive amounts of low energy aura, they produce small amounts of high energy aura. When their aura coated fists then comes into contact with something(or someone), the energy is released, sometimes just as kinetic energy, or as thermal and sound energy as well(hence the explosions from adult Gon and Uvo's attacks).
