Atomic mass and molecular mass are the ratios and have no units. Mol. mass =( text Wt. of one molecule of the substance/1 / 2 × text wt. of one atom of C-12)

Q. Assertion : S.I. unit of atomic mass and molecular mass is kilograms.
Reason : Atomic mass is equal to the mass of $6.023 \times 1 0^{24}$ atoms.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Atomic mass and molecular mass are the ratios and have no units.

Mol. mass $= \frac{Wt. of one molecule of the substance}{1/2 \times wt. of one atom of C - 12}$
