The rotten smell of a decaying animal carcass is partially due to a nitrogen-containing compound called putrescine. Elemental analysis of putrescine showed that it consisted of 54.50% X, 13.73% H, and 31.77% N. find empirical formula

Explanation:

Hello,

In this case, considering the given percentages, we compute the mole ratios as shown below:

Now, by dividing all the mole ratios by the smallest ratio, we obtain the subscripts for the required empirical formula as shown below:

Therefore, the empirical formula turns out:

Best regards.
