# The ratio of carbon atoms to hydrogen atoms to oxygen atoms in a molecule of dicyclohexyl maleate is 4 to 6 to 1. What is its molecular formula if its molar mass is 280 g?

#### Risposta:

C_16H_24O_4.....

#### Spiegazione:

We have been given an empirical formula of C_4H_6O. We know that the molecular formula is always a whole number multiple of the empirical formula. Thus {4xx12.01+6xx1.01+16.0}xxn=280*g*mol^-1. My arithmetic gives n=4. And thus the molecular formula is C_16H_24O_4.
