Question

find the percentage of nitrogen in ammonia​

Answer 1

Answer:

Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH 3 is about 17. From this we find that the mass percentage of N in NH 3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table
