After the shuttle disaster, an unknown compound residue was removed from a piece of the debris. Upon analysis, it was found to contain 2.61 g of carbon, 6.09 g of nitrogen, and 1.31 g of hydrogen. What is its empirical formula?

The final empirical formula is

Explanation:

Given

The amount of carbon, nitrogen and hydrogen in a given compound is as follows

C:N:H

On simplifying the ration values  we get

So the final ratio is

The final empirical formula is

the answer is b. dilution
