Assertion (A): Laboratory reagents are usually made up to a specific molarity rather than a given molality.
Reason (R): The volume of a liquid is more easily measured than its mass.
Reason (R): The volume of a liquid is more easily measured than its mass.
View answer and explanation
Correct option: A
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Option A (Both (A) & (R) are true and the (R) is the correct explanation of the (A)) is correct because molarity is preferred due to the ease of volume measurement, which is the reason why laboratory reagents are made to specific molarities.
