Question

what is the percentage of composition of the elements in ammonia

Answer 1

82.24% percent composition of N and17.76% percent composition of H .
Calculation :-

First of all you will want to add the atomic massfor all the elements in NH3 . This can be readily obtained with a periodic table.

Let's take the elements and add their masses up:

14.007 + 1.008(3) = 17.031

Now we will divide each individual atom with the mass we got in step one and multiply by 100.

14.007/17.031 x 100 = 82.24414...%
1.008(3)/17.031 x 100 = 17.75586...%

Therefore, we can say there is 82.24% of N and 17.76% of H.
