The rotten smell of a decaying animal carcass is partially due to a nitrogen-containing compound called putrescine. Elemental analysis of putrescine indicates that it consists of 54.50% C, 13.73% H, and 31.77% N. Calculate the empirical formula of putrescine.
Here, we have to calculate the empirical formula of putrescine.
Step 1: Assume 100 g of the compound is present.
C= 54.50 g
H = 13.73 g
N = 31.77 g
Conversion of the masses to moles by using the molar mass for each element as a
54.50 g of C x = 4.537 mol C
13.73 g of H x = 13.621 mol H
31.77 g of N x = 2.269 mol N
Step 3: The pseudo empirical formula of the compound is
