Which one is heavier? 1 mole of pbd4,1 mole of H2 And 1 mole of pb(no3)2

Clearly, Pb(NO3)2 is the heaviest molecule among those given.

So a mole will weigh more than the others.
Better review just what a mole is.

None of them is heavy🥲

<<It shocked me too>>

Teach me what is pbd4

how can you tell which is heavier

None of them is heavier

hmm explain how to know the heaviest mol

Sorry chemistry Not maths
