Question

If the mass ratio of nitrogen to hydrogen in ammonia is 4.7:1. if a sample of ammonia contains 10.0 gram of h, how many grams of n does it contain?

Answer 1

The amount, in grams, of N that the sample will contain will be 2.1 grams.

Stoichiometric mass ratio

According to the problem. the mass ratio of H and N in ammonia is 4.7:1.

In other words, every 4.7 grams of H in ammonia must have 1 gram of N.

Now, in a particular ammonia sample, 10 grams of H is present.

The amount of N present can be calculated from the standard mass ratio.

4.1 grams H = 1 gram N

10 grams H = x

4.1x = 1 x 10

        x = 10/4.1

             x = 2.1 grams

Thus, the mass of nitrogen in the ammonia sample will be 2.1 grams.
