A compound with an empirical formula of C4H4O and a molar mass of 136 g/mol. What is the molecular formula of this compound?
fredd [130]

Answer:

C8H8O2

Explanation:

The molecular formula of a compound is simply a multiple of the empirical formula as shown below:

Molecular formula => [C4H4O]n

From the question given, we were told that molar mass of the compound is 136g/mol. This implies that:

[C4H4O]n = 136

Now, let us find the value of n in order to obtain the desired result. This is illustrated below:

[C4H4O]n = 136

[(12x4) + (4x1) + 16]n = 136

[48 + 4 + 16]n = 136

68n = 136

Divide both side by the coefficient of n i.e 68

n = 136/68

n = 2

Therefore the molecular formula is

=> [C4H4O]n

=> [C4H4O]2

=> C8H8O2
