Atomic weight is Ar of the atom (what you see on the periodic table)
atomic weight<span> is relative </span>atomic mass, so yeah same thing
Calculating the molar mass of naphthalene (C10H8)
molar mass = 10 x (12.01) + 8(1.008)
= 120.1 + 8.064 = 128.164 g/mol
that's right.............:)
it is not true my brotha/sista
