A) C₆₀H₁₂₀O₆₀
B) C₆H₁₂O₆
C) C₆₀H₁₀₂O₅₁
D) C₆₀H₁₀₀O₅₀
E) C₆₀H₁₁₁O₅₁

Question

Quizplus · Accepted Answer

A polymer made by linking ten glucose molecules together by dehydration reactions would have the molecular formula (C₆H₁₂O₆)n, where n is the number of glucose molecules linked together. Since there are ten glucose molecules linked together in this polymer, the molecular formula would be (C₆H₁₂O₆)₁₀, which simplifies to C₆₀H₁₀₂O₅₁.

The Molecular Formula for Glucose Is C₆H₁₂O₆
