The molecular weight of sucrose ( C₁₂H₂₂O₁₁ ),table sugar,is ________ amu (rounded to one decimal place).

Question

Quizplus · Accepted Answer

To calculate the molecular weight of sucrose, we need to add the atomic weights of each element within the molecule. By adding the atomic weights of carbon, hydrogen, and oxygen in one molecule, we get:

12.01 (C) + 1.01 x 22 (H) + 16.00 x 11 (O) = 342.3

Therefore, the molecular weight of sucrose is 342.3 amu, which is closest to Option C (342.3).
