Question

Assertion (A) Experimentally determined molar mass is always lower than the true value.
Reason (R) Lower molar mass is due to dissociation of solute into ions.

• A. Both $A$ and $R$ are correct, $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct, $R$ is not the correct explanation of $A$.
• C. $A$ is correct, $R$ is incorrect.
• D. $A$ is incorrect, $R$ is correct.

Answer 1
