If his molecular structure were the density of steel, his weight would be 1470 pounds. Even if his density were only that of concrete, he would weigh 450 pounds. He doesn’t seem to break furniture all the time by sitting on it so simply saying “dense molecular structure” doesn’t provide the whole answer.
For Clark weight can be whatever he wants it to be with his levitation abilities... so he may weigh a ton or more but he could fool even balances. Though I do agree that 'dense molecular structure' is a very poor explanation. Our own cells are very highly concentrated with organelles, proteins and more... how much more can realistically be packed into his cells?
I would lean more towards a barrier method that is external (aka the 'aura' mentioned in some fics, magnetic shield or something similar?) or some sort of cell wall that strengthens his cells but maintains the flexibility of the tissue while giving it added resilience. But then how would kryptonite remove that?
On another note... the metallic clang heard in Return of the Prankster (and maybe elsewhere, I just specifically remember it from when he's frozen and shoved off the balcony) is just completely unrealistic to me.
