Question

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: C, 54.50%, H, 13.73%, and N, 31.77%. Calculate the empirical formula of putrescine.

Answer 1

C, 54.50%, H, 13.73%, and N, 31.77%.
Take 100 g sample.
C = 54.50 g
H = 13.73 g
N = 31.77 g Now convert to mols.
mols C = C = 54.50 g/12.01 = 4.54
mols H = 13.73 g/1.008 = 13.62
mole N = 31.77 g/14.01 = 2.27
Find the ratio of these elements with whole numbers being no less than 1.The easy way to do that is to divide the smallest number by itself. Follow suit with the others.
mols C = 4.54/2.27= 2.00
mols H = 13.62/2.27 = 6.00
mole N = 2.27/2.27 = 1.00
So the formula is ............
