How many nitrogen atoms are present in a sample of 1,983 hydrogen atoms, if ammonia is a compound consisting of a 1:3 ratio of nitrogen and hydrogen atoms?

Answer 1

The answer is #661# atoms of #N#.

Since ammonia (#NH_3#) has a #1:3# ratio of Nitrogen to Hydron atoms, and since the number of #H# atoms is 1983, the number of #N# atoms is

#1983# #H# #at oms# # * (1 at om N)/(3 at oms H) = 661# atoms #N#.

To find the number of nitrogen atoms, divide the number of hydrogen atoms by 3, since the ratio of nitrogen to hydrogen in ammonia is 1:3.

Number of nitrogen atoms = (1983 hydrogen atoms) / 3 = 661 nitrogen atoms.

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.
