Question

what percent of Nitrogen present in aluminium nitrates (aluminium=27 N= 14)​

Answer 1

Answer:

I think your question is for aluminium Nitride, because you haven't been given mass of oxygen. Therefore

Explanation:

Aluminum nitride- AlN

Molecular mass of AlN=27+14=41

% of nitrogen= atomic weight of N ÷ molecular mass of AlN

= 14/41 = 34.14%

Answer 2

Answer:

formula of aluminum nitrate is what

Al(NO3)3

aluminium percent =(42+96)/42+96+27*100

=138/165*100

=83

now, aluminum percent =100-83=17
