plzzzzzz someone help me for this......​

Answer 1

Answer:

In ammonia, nitrogen and hydrogen are always present in the ratio 14:3 by mass

Let's assume mass of a Nitrogen atom is X and that of a Hydrogen atom is Y.

From the law of constant proportion,

3Y:X=3:14⇒X=14×Y

Mass of a Nitrogen atom (X) is 14 times that of a Hydrogen atom (Y).
