• A. Molarity
• B. Heat capacity
• C. Mass

Answer 1

The correct option is A

Molarity

Explanation for correct option:

A. Molarity

Extensive property:

• Extensive properties are the physical properties that are dependent on the mass of a matter.
• Examples of extensive properties are Entropy as well as Enthalpy.

Intensive property:

• Intensive properties are those physical characteristics that are independent of the mass of any substance/matter.
• Examples of intensive properties are Pressure as well as temperature.

Molarity is an intensive property as it is independent of the mass and it gives the value of the concentration of a solution.

Explanation for incorrect options:

B. Heat capacity is an extensive property as it depends on the mass of a substance.

C. Mass is an extensive property.

Hence, the correct option is A i.e. Molarity is not an extensive property.
