Question

How do I get the molar mass of urea?

Answer 1

Urea structure:

Urea has four elements which are carbon, nitrogen, oxygen, and hydrogen. It has a molar mass of 60.06 g/mole and has two amide groups and a carbonyl group. The structure of the compound is given below

H₂N−(C=O)−NH₂

Molar Mass

We know that

Atomic mass of C=12
Atomic mass of O=16
Atomic mass of N=14
Atomic mass of H=1

Molecular mass = sum of all the atomic masses of atoms.
=12+16+2[14+2×1]12+16+32
=60

Answer

Molar mass of urea is 60 g/mol
