1. What is Sucrose Molar Mass?

Sucrose (common table sugar) has the molecular formula C₁₂H₂₂O₁₁ and a molar mass of 342.3 g/mol. This represents the mass of one mole of sucrose molecules.

2. How is Molar Mass Calculated?

The molar mass is calculated by summing the atomic masses of all atoms in the molecule:

Where:

• Carbon (C) — 12 atoms × 12.01 g/mol = 144.12 g/mol
• Hydrogen (H) — 22 atoms × 1.008 g/mol = 22.176 g/mol
• Oxygen (O) — 11 atoms × 16.00 g/mol = 176.00 g/mol
• Total = 342.296 g/mol ≈ 342.3 g/mol

3. Importance of Molar Mass

Details: Molar mass is fundamental in chemistry for converting between mass and moles, determining empirical formulas, calculating solution concentrations, and understanding stoichiometry in chemical reactions.

4. Using the Calculator

Tips: Enter the mass of sucrose in grams to calculate the number of moles and molecules. The calculator uses Avogadro's number (6.022 × 10²³) for molecular calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between molar mass and molecular weight?
A: Molar mass is the mass of one mole of a substance in grams, while molecular weight is the mass of one molecule in atomic mass units (amu).

Q2: Why is sucrose's molar mass important in food science?
A: It's crucial for calculating sugar concentrations, nutritional labeling, and understanding sweetness intensity in food products.

Q3: How does molar mass affect physical properties?
A: Higher molar mass generally increases boiling point, melting point, and viscosity while decreasing volatility.

Q4: Can this calculator be used for other sugars?
A: No, this calculator is specific to sucrose. Other sugars like glucose (C₆H₁₂O₆) and fructose have different molar masses.

Q5: What is Avogadro's number and why is it important?
A: Avogadro's number (6.022 × 10²³) represents the number of particles in one mole of any substance, allowing conversion between atomic and macroscopic scales.
