1. What Is Molar Mass?

Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule.

2. How To Calculate Molar Mass Of Urea

The molar mass of urea (CO(NH₂)₂) is calculated using the formula:

For urea CO(NH₂)₂:

• Carbon (C): 1 atom × 12.01 g/mol
• Oxygen (O): 1 atom × 16.00 g/mol
• Nitrogen (N): 2 atoms × 14.01 g/mol
• Hydrogen (H): 4 atoms × 1.008 g/mol

3. Atomic Masses Used In Calculation

Standard Atomic Masses:

• Carbon (C): 12.01 g/mol
• Oxygen (O): 16.00 g/mol
• Nitrogen (N): 14.01 g/mol
• Hydrogen (H): 1.008 g/mol

4. Step-by-Step Calculation

Calculation for Urea:
1 × 12.01 = 12.01 g/mol (Carbon)
1 × 16.00 = 16.00 g/mol (Oxygen)
2 × 14.01 = 28.02 g/mol (Nitrogen)
4 × 1.008 = 4.032 g/mol (Hydrogen)
Total = 12.01 + 16.00 + 28.02 + 4.032 = 60.06 g/mol

5. Frequently Asked Questions (FAQ)

Q1: What is the chemical formula of urea?
A: The chemical formula of urea is CO(NH₂)₂, which represents one carbon atom, one oxygen atom, two nitrogen atoms, and four hydrogen atoms.

Q2: Why is molar mass important?
A: Molar mass is essential for converting between mass and moles in chemical calculations, stoichiometry, and preparing solutions of specific concentrations.

Q3: Are atomic masses exact numbers?
A: No, atomic masses are weighted averages that account for different isotopes of each element found in nature.

Q4: Can I use this calculator for other compounds?
A: Yes, you can modify the number of atoms for each element to calculate the molar mass of any chemical compound.

Q5: What is urea used for?
A: Urea is widely used as a nitrogen-release fertilizer, in animal feed, in cosmetics, and as a raw material in the chemical industry.
