Question

Molecular mass defined as?

Answer 1

the molecular mass ,is the sum the atomic mass of each atom of the molecule.

example - find the M of the ammonia

molecular formula of ammonia =NH3

N =1×14= 14. (atomic no. of N = 14)

H =3×1 = 3. (atomic no.of H = 1)

M of the ammonia 14 +3 = 17

Answer 2

Answer:

Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
