Q. Assertion : An atomic mass and molecular mass are unit less.
Reason : Mol. mass is equal to the mass of $6.023 \times 10^{23}$ atoms.

Solution:

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