Molecular Mass of Sucrose: Sucrose, commonly known as table sugar, is one of the most familiar and widely used carbohydrates in the world. Its sweet taste makes it a favorite ingredient in many culinary creations, from desserts to beverages.

But beyond its taste, sucrose has a fascinating chemical structure with a specific molecular mass that plays a crucial role in various applications and industries. In this article, we will explore the molecular mass of sucrose and its significance in both the culinary world and scientific research.

Molecular Mass of Sucrose

The Chemical Structure of Sucrose

Sucrose is a disaccharide, which means it consists of two simpler sugar molecules chemically bonded together. Specifically, it is composed of one molecule of glucose and one molecule of fructose linked by a glycosidic bond. This unique combination of glucose and fructose is what gives sucrose its distinctive sweet taste.

The molecular formula of sucrose is C12H22O11, representing 12 carbon (C) atoms, 22 hydrogen (H) atoms, and 11 oxygen (O) atoms. The molecular mass of sucrose is calculated by summing the atomic masses of these elements in the given ratio.

Calculating the Molecular Mass of Sucrose (C12H22O11)

To determine the molecular mass of sucrose, we need to consider the atomic masses of carbon (C), hydrogen (H), and oxygen (O):

• The atomic mass of carbon (C) is approximately 12.01 atomic mass units (amu).
• The atomic mass of hydrogen (H) is approximately 1.01 amu.
• The atomic mass of oxygen (O) is approximately 16.00 amu.

Now, let’s calculate the mol mass of sucrose:

The mol Mass of Sucrose = (12 × Atomic Mass of C) + (22 × Atomic Mass of H) + (11 × Atomic Mass of O)

mol Mass of Sucrose = (12 × 12.01 amu) + (22 × 1.01 amu) + (11 × 16.00 amu)

mol Mass of Sucrose ≈ 342.30 amu

Therefore, the mol mass of sucrose is approximately 342.30 atomic mass units (amu).
