In basic Chemistry (Mole Concept), calculating the molar mass of complex molecules is a highly crucial skill. Urea, mathematically written as NH₂CONH₂, is the most heavily famous nitrogen-rich organic fertilizer used globally.
Urea holds massive historical importance: In 1828, scientist Friedrich Wöhler successfully synthesized massive Urea from inorganic ammonium cyanate, completely violently destroying the old myth that 'organic chemicals can only be made by living things'.
The chemical formula of Urea is CH₄N₂O (or structurally NH₂CONH₂). To find the total massive molecular mass, we must add the individual atomic masses of every single atom inside.
Here are the standard heavy atomic masses of the elements:
Let's count the atoms in NH₂CONH₂:
Now, sum them all heavily up: 12.01 + 28.02 + 4.04 + 16.00 = 60.07 g/mol
For standard high school calculations, you can safely round it off. The highly accepted molar mass of Urea is exactly 60 g/mol.
Because the mass of Nitrogen is 28 out of the total 60, Urea mathematically contains an incredibly massive **46.6% pure Nitrogen**, making it the absolute best solid fertilizer for poor farmers.
