Answer 1

hey dude,


⭐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.

$<h3>Molecular Weight </h3>$

The molecular weight of a substance may be defined as the average relative mass of its molecule as compared to the mass of an atom of carbon ( 12C ) taken as 12.

Molecular weight expresses as to how many times a molecule of the substance is heavier than 1/12 th of the mass of an atom of carbon.

For Example : a molecule of CO2 is 44 atom. Therefore, the molecular weight of Carbon dioxide is 44 a. m. u.
