Molecular Mass of Urea: Urea (CH₄N₂O) is one of the most essential organic compounds, widely used in both biological and industrial fields. Known primarily as a fertilizer in agriculture, urea also plays a crucial role in the human body as part of the nitrogen excretion process through urine.
For students preparing for competitive exams like NEET, JEE, and Olympiads in 2025, understanding the molecular mass of urea is fundamental in mastering chemistry, especially in stoichiometry, organic chemistry, and biochemistry.
What is the Molecular Formula of Urea?
The chemical formula of urea is CH₄N₂O, which indicates that a single molecule of urea contains:
-
1 atom of Carbon (C)
-
4 atoms of Hydrogen (H)
-
2 atoms of Nitrogen (N)
-
1 atom of Oxygen (O)
Understanding this formula is the first step toward calculating its molecular mass.
How to Calculate the Molecular Mass of Urea?
To find the molecular mass of any compound, we multiply the number of atoms of each element by their respective atomic masses (as per the modern periodic table) and sum them up.
Here’s the step-by-step calculation for urea (CH₄N₂O):
Calculation:
= (1 × 12.01) + (4 × 1.008) + (2 × 14.01) + (1 × 16.00)
= 12.01 + 4.032 + 28.02 + 16.00
= 60.06 g/mol
Molecular Mass of Urea = 60.06 g/mol
