Question
Molecular mass can be determined by
- Determining the atomic mass of each element present in a molecule.
- Deterring the mass of molecule.
- Comparing the atomic mass of each element.
- By taking average atomic mass of each element in a molecule.
Hint:
A molecule is made up of atoms.
The correct answer is: Determining the atomic mass of each element present in a molecule.
- The molecular weight of a molecule is the mass expressed in the unified atomic mass unit (1/12th of the mass of an atom of the isotope carbon-12, also known as Daltons or Da).
- The sum of the atomic masses of all atoms in a molecule, based on a scale where hydrogen, carbon, nitrogen, and oxygen have atomic masses of 1, 12, 14, and 16, respectively.
