Question

Calculate percentage elements present in ammonium chloride (NH₄Cl).
(N=14, H=1, Cl=35.5)

Answer 1

N=16
H=1
Cl=35.5
Total mass of ammonium chloride=14+[1*4]+35.5
=53.5
% of nitrogen=mass of nitrogen in compund
----------------------------------------... *100
total mass of compund
=14/53.5 * 100
=26.168 g
=26.17 g.

Answer 2

heyaaa !!!!!

N = 16
H = 1
Cl = 35.5

Total mass of ammonium chloride = ( 14 + 1×4 + 35.5 ) = 53.5

percentage of nitrogen = mass of nitrogen in compound / total mass of compound × 100

= 14 / 53.5 × 100

= 26.168 g
= 26.17 g

by using this formulae u can find for other elements also...
