  1. Question 1

    Q1. During the synthesis of sucrose from glucose and fructose (C6H12O6 each), one molecule of water is eliminated. What is the resulting molecular mass of sucrose?

    • A) 360 amu
    • B) 342 amu
    • C) 180 amu
    • D) 324 amu

    Answer: 342 amu

    Explanation: The formula for a disaccharide is 2(C6H12O6) minus H2O, resulting in 342 amu. Option A is the weight of two separate hexoses without dehydration.
