In fact the exact molar mass of ammonia is 17.0304 g/mol. this is because ammonia has various isotopes of hydrogen and nitrogen, thus increasing its weight.

Ammonia is NH3. That's one nitrogen atom and three hydrogen atoms. Nitrogen has an atomic mass of 14 and hydrogen has an atomic mass of 1, so the molecular mass of ammonia is 14 + 3*1 = 17. Note that "molecular mass" is a more correct term than "molecular weight."
