A compound has a chemical composition of 72 g carbon, 12 g hydrogen, 16 g oxygen. What is the empirical formula? Answer Asap
Choices are :
A. C6H12O
B. C1.5H6O
C. CHO
D. No answer text provided.
E. C6H12O2

The empirical formula is the formula given, but only counts one of each.

The question given gives us a composition of 72g Carbon, 12g Hydrogen, & 16g oxygen.

Carbon = C, Hydrogen = H, Oxygen = O

-------------------------------------------------------------------------------------------------------------------

Remember that the empirical formula only gives one of each, and the three elements inside the question given is Carbon, Hydrogen, and Oxygen. This means that your answer is:

C. CHO: 1 Carbon, 1 Hydrogen, 1 Oxygen.

(C) is your answer
