Detailed Solution

Step-by-Step Calculation:

Urea has the molecular formula NH₂CONH₂, which consists of:

  • Carbon (C) = 1 atom
  • Hydrogen (H) = 4 atoms
  • Nitrogen (N) = 2 atoms
  • Oxygen (O) = 1 atom

Now multiply the number of atoms by the atomic mass of each element:

ElementNo. of AtomsAtomic Mass (g/mol)Total Mass (g/mol)
Nitrogen (N)214.012 × 14.01 = 28.02
Hydrogen (H)41.0084 × 1.008 = 4.032
Carbon (C)112.011 × 12.01 = 12.01
Oxygen (O)116.001 × 16.00 = 16.00

Final Step: Add All the Values

Molar Mass of Urea = 28.02 + 4.032 + 12.01 + 16.00 = 60.06 g/mol

Final Answer:

The molar mass of urea is 60.06 g/mol.
