Assertion : S.I. unit of atomic mass and molecular mass is kilograms. Reason : Atomic mass is equal to the mass of 6.023 10²⁴ atoms.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Atomic mass and molecular mass are the ratios and have no units. Mol. mass = Wt. of onemolecule of the substance 1 / 12 wt. of oneatom of C -12 .
