The urine of horses are mixed with an excess of hydrochloric acid, after some time, a yellowish-brown crystalline precipitate, which have an unpleasant odor, that can't be removed by simply washing with water.

This new compound has the following composition (parts by mass):

Nitrogen: 7.337 parts in 100 parts
Carbon: 63,032 parts in 100 parts
Hydrogen: 5.000 parts in 100 parts
Oxygen: 24,631 parts in 100 parts

Thx u so much for your help :)

What is the empirical formula of this compound

(Sry, I forgot something)

You're welcome! It seems like you're interested in the composition of a compound formed when horse urine is mixed with hydrochloric acid. The composition of this compound includes nitrogen, carbon, hydrogen, and oxygen.

To determine the composition, we can calculate the percentage of each element in the compound using the given parts by mass. The parts by mass correspond to the percentage by mass of each element.

1. Calculate the percentage of nitrogen (N):
Nitrogen (N) = 7.337 parts / 100 parts × 100% = 7.337%

2. Calculate the percentage of carbon (C):
Carbon (C) = 63.032 parts / 100 parts × 100% = 63.032%

3. Calculate the percentage of hydrogen (H):
Hydrogen (H) = 5.000 parts / 100 parts × 100% = 5.000%

4. Calculate the percentage of oxygen (O):
Oxygen (O) = 24.631 parts / 100 parts × 100% = 24.631%

So, the composition of the compound is approximately:
Nitrogen (N) = 7.337%
Carbon (C) = 63.032%
Hydrogen (H) = 5.000%
Oxygen (O) = 24.631%

I hope this helps! Let me know if you have any further questions.
