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

Q. Assertion : An atomic mass and molecular mass are unit less.
Reason : Mol. mass is equal to the mass of $6.023 \times 1 0^{23}$ atoms.

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

If the Assertion is correct but Reason is incorrect.

If the Assertion is incorrect and Reason is correct.

Atomic mass and molecular mass are the ratios and have no units.
Mol. mass $= \frac{Wt. of one molecule of the substance}{\frac{1}{12} \times wt. of one atom of C - 12}$
