The empirical formula of Glucose C6H12O6 is:
Correct answer: C. CH2O
- A. C6H12O6
- B. CHO
- C. CH2O
- D. CH2O2
Explanation
The molecular formula for glucose is C6H12O6. The subscripts represent a multiple of the empirical formula. To determine the empirical formula, we have to divide the subscripts by the greatest common factor which in this case is 6 giving us CH2O. The molecular formula of glucose is C6H12O6 and the empirical formula of glucose is CH2O. We can derive a relation between the Molecular formula and the empirical formula of glucose. We can derive a general expression as, Molecular formula = n × empirical formula where n is a whole number.C6H12O6 = 6 × CH2O

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
