Answer:
- We need to know the molecular formula of urea to compute its molar mass.
- Urea’s molecular formula is NH2CONH2.
- To get the molar mass of any chemical, we must first determine the molecular weight of the various elements that make up the molecule.
- Carbon, hydrogen, oxygen, and nitrogen are the individual elements in the chemical formula of urea.
- Hydrogen, carbon, nitrogen, and oxygen have molecular weights of 1, 12, 14, and 16, respectively.
- As a result, the molecular weight of urea can be simply computed, as shown below.
=4 (H) + 2 (N) + (O) + (C)
= 4 (1) + 2(14) + (16) + (12)
= 4 + 28 + 16 + 12
= 60
As a result, the urea’s molecular mass is 60 g/mol.
