Concept Introduction :
Empirical formula of a molecule is the smallest unit which is repeated in the molecule.
Molecular formula of a compound is the representation of the molecule with the number of different atoms present in the molecule.
Molecular formula
Answer to Problem 60A
The empirical formula of the compound is C3H7N2O.
Explanation of Solution
0.7221 g sample contains 0.2990 g, 0.058499 g, 0.2318 g and 0.1328 g C, H, N and O respectively Moles of C
Moles of H
Moles of N
