Answer to Question #134118 in Organic Chemistry for Klaudja

Question

a chemical compound has 54.55% carbon and 9.09% hydrogen. Determine the chemical formula if its molar mass is 70g / mol

Answer 1

Solution.

$n(C) = \frac{54.55}{12} = 4.546$

$n(H) = \frac{9.09}{1} = 9.09$

$n(C):n(H):n(X) = 3.18:6.36: \frac{25.452}{A(X)} = 1:2:\frac{8}{A(X)}$

By iterating from the element nitrogen to chlorine, the most suitable formula for this compound is C3H6N2. So, X is N.

Answer:

C3H6N2
