Question

heya mates!!
what is molecular weight?


​

Answer 1

Answer:

molecular weight is the sum of atomic masses of elements in a molecule

Answer 2

Molecular weight is the weight of an molecule.i.e. combination of atoms .

eg H2O .

it has 2H atoms

and 1O atom

weight of these atoms is actually addition of their electrons and protons. .

atomic weight of O is 16 and of H is 1 so the total molecular weight of H20 will be

(1)×2 + 16

=18gram/mol
