Question

Calculate the molecular formula for a carbohydrate composed of multiple glucose monomers.

A) C₆H₁₂O₆
B) C₆H₁₁O₅
C) C₆H₁₂O₄
D) C₆H₁₀O₆

Answer 1

The molecular formula for a carbohydrate composed of multiple glucose monomers is C6H12O6.

Step-by-step explanation:

The molecular formula is C6H12O6 because one molecule actually contains 6 C, 12 H, and 6 O atoms. The simplest whole-number ratio of C to H to O atoms in glucose is 1:2:1, so the empirical formula is CH2O.
