The Gram Molecular Weight of Urea, CO (NH₂ )₂ Is

Question

The gram molecular weight of urea, CO (NH2)2is about
A) 48 g mol-1
B) 48 daltons
C) 48 g
D) 60 g mol-1
E) 180 g mol-1

Accepted Answer

The molecular formula of urea is CO(NH2)2. To calculate its molar mass: Carbon (C) = 12.01 g/mol, Oxygen (O) = 16.00 g/mol, Nitrogen (N) = 14.01 g/mol (2 N atoms = 28.02 g/mol), and Hydrogen (H) = 1.008 g/mol (4 H atoms = 4.032 g/mol). Adding these gives a total of 60.05 g/mol, which is approximately 60 g/mol.
