What is the percent composition of Ammonia, #NH_3#?

Answer 1

82.24% percent composition of #N# and 17.76% percent composition of #H#.

First of all you will want to add the atomic mass for all the elements in #NH_3# . 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#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
