1. What is Molar Mass?

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). For glucose (C₆H₁₂O₆), it's the sum of the atomic masses of all its constituent atoms.

2. How to Calculate Molar Mass

The calculation formula:

Where:

• \( n_C \) — Number of carbon atoms
• \( n_H \) — Number of hydrogen atoms
• \( n_O \) — Number of oxygen atoms
• 12.011 — Atomic mass of carbon (g/mol)
• 1.008 — Atomic mass of hydrogen (g/mol)
• 15.999 — Atomic mass of oxygen (g/mol)

3. Glucose Molecular Structure

Details: Glucose is a simple sugar with the molecular formula C₆H₁₂O₆. It's the most abundant monosaccharide and an important carbohydrate in biology.

4. Using the Calculator

Tips: Enter the number of each type of atom in the molecule. Default values show the calculation for standard glucose. You can modify these to calculate for other molecules.

5. Frequently Asked Questions (FAQ)

Q1: Why is glucose's molar mass important?
A: It's essential for preparing solutions with specific molar concentrations in chemistry and biology experiments.

Q2: How accurate is this calculation?
A: Using standard atomic weights, the calculation is accurate to about 2 decimal places for most laboratory purposes.

Q3: Does this work for other sugars?
A: Yes, just change the atom counts (e.g., for fructose which also has the formula C₆H₁₂O₆).

Q4: What about isotopic variations?
A: This uses average atomic masses. For precise work with specific isotopes, use exact isotopic masses.

Q5: How does this relate to molecular weight?
A: Molar mass and molecular weight are numerically identical but molar mass has units (g/mol).
