Here's how to determine the number of water molecules released when sucrose (C12H22O11) is formed:

Understanding the Process

Sucrose is a disaccharide formed by the combination of two simpler sugars: glucose (C6H12O6) and fructose (C6H12O6). The reaction is a dehydration synthesis, meaning a water molecule is removed:

Glucose + Fructose → Sucrose + Water

Calculating Water Molecules

1. Write the balanced chemical equation:

C6H12O6 (glucose) + C6H12O6 (fructose) → C12H22O11 (sucrose) + H2O (water)

2. Notice the stoichiometry: The equation shows that one molecule of water is released for every molecule of sucrose formed.

Therefore, when one molecule of C12H22O11 (sucrose) is formed, one molecule of water is released.
