Question

What is molecular weight of an compound?


​

Answer 1

⭐Molecular weight is a measure of the sum of the atomic weight values of the atoms in a molecule.

⭐Molecular weight is either unitless or expressed in terms of atomic mass units (amu) or Daltons (Da)

⭐For example :--

➡The chemical formula for water is H2O, which means this molecule has 3 atoms: 2 of hydrogen (H) and 1 oxygen (O) atom.

✨The base SI unit for molar mass is kg/mol.

✨ That is, the weight of a substance for 6.02214076×10^23 molecules or atoms of that substance, which is also called Avagadro number.

⭐Avagadro number is equal to 6.02214076×10^23 particles.
