Question

The molecular weight of ammonia is.......
1. 17 amu
2. 19 amu
3. 15 amu

Answer 1

Answer:

The molecular weight of ammo night I e. NH3 is 14+3 = 17 amu

Answer 2

Answer:

[1] 17 AMU.

Explanation:

FORMULA OF AMMONIA = NH₃

MASS OF N = 14 AMU

MASS OF H = 1 AMU.

MASS OF NH₃ = 14+3*1

                        = 14+3

                        = 17 AMU.

THEREFORE THE MOLECULAR MASS OF NH₃ IS 17 AMU.
